Notes on individual issues:
|
|
===========================
|
|
|
|
security-libs/java.security:
|
|
|
|
JDK-8281658: Add a security category to the java -XshowSettings option
|
|
======================================================================
|
|
|
|
The `-XshowSettings` launcher option now has a 'security' category, allowing
|
|
the following arguments to be passed:
|
|
|
|
* -XshowSettings:security or -XshowSettings:security:all: show all security settings and continue
|
|
* -XshowSettings:security:properties - show security properties and continue
|
|
* -XshowSettings:security:providers - show static security provider settings and continue
|
|
* -XshowSettings:security:tls - show TLS related security settings and continue
|
|
|
|
The output will include third-party security providers if they are
|
|
included in the application class path or module path, and configured
|
|
in the java.security file.
|
|
|
|
JDK-8316138: Add GlobalSign 2 TLS root certificates
|
|
===================================================
|
|
The following root certificates have been added to the cacerts
|
|
truststore:
|
|
|
|
Name: GlobalSign
|
|
Alias Name: globalsignr46
|
|
Distinguished Name: CN=GlobalSign Root R46, O=GlobalSign nv-sa, C=BE
|
|
|
|
Name: GlobalSign
|
|
Alias Name: globalsigne46
|
|
Distinguished Name: CN=GlobalSign Root E46, O=GlobalSign nv-sa, C=BE
|
|
|
|
security-libs/javax.security:
|
|
|
|
JDK-8328638: Fallback Option For POST-only OCSP Requests
|
|
========================================================
|
|
JDK-8179503, introduced in OpenJDK 17, added support for using the
|
|
HTTP GET method for OCSP requests. This was turned on unconditionally
|
|
for small requests.
|
|
|
|
RFC 5019 and RFC 6960 explicitly allow and recommend the use of HTTP
|
|
GET requests. However, some OCSP responders have been observed to not
|
|
work well with such requests.
|
|
|
|
With this release, the JDK system property
|
|
`com.sun.security.ocsp.useget` is introduced. The default setting is
|
|
'true' which retains the current behaviour of using GET requests for
|
|
small requests. If the property is instead set to 'false', only HTTP
|
|
POST requests will be used, regardless of size.
|
|
|
|
This option is non-standard and may be removed again if problematic
|
|
OCSP responders are no longer an issue.
|
|
|
|
infrastructure/build:
|
|
|
|
JDK-8326891: Prefer RPATH over RUNPATH for $ORIGIN rpaths in internal JDK binaries
|
|
==================================================================================
|
|
Native executables and libraries in the JDK use embedded runtime
|
|
search paths to locate required internal JDK native libraries. On
|
|
Linux systems, there are two ways of specifying these search paths;
|
|
DT_RPATH and DT_RUNPATH.
|
|
|
|
The main difference between the two options is that paths specified by
|
|
DT_RPATH are searched before those in the LD_LIBRARY_PATH environment
|
|
variable, whereas DT_RUNPATH paths are considered afterwards. This
|
|
means the use of DT_RUNPATH can allow JDK internal libraries to be
|
|
overridden by libraries of the same name found on the LD_LIBRARY_PATH.
|
|
|
|
Builds of earlier OpenJDK releases left the choice of which type of
|
|
runtime search path to use down to the default of the linker. With
|
|
this release, the option `--disable-new-dtags` is explicitly passed to
|
|
the linker to avoid setting DT_RUNPATH.
|
|
|
|
tools/jpackage:
|
|
|
|
JDK-8295111: dpkg appears to have problems resolving symbolically linked native libraries
|
|
=========================================================================================
|
|
The jpackage tool uses `dpkg -S` to lookup which package provides a
|
|
particular file on Debian and Ubuntu systems. However, on newer Debian
|
|
and Ubuntu systems, `dpkg -S` does not resolve symlinks. In this
|
|
OpenJDK release, jpackage now resolves symlinks before passing the
|
|
real path of the file to dpkg.
|
|
|
|
hotspot/gc:
|
|
|
|
JDK-8314573: G1: Heap resizing at Remark does not take existing eden regions into account
|
|
=========================================================================================
|
|
To comply with the settings of `-XX:MinHeapFreeRatio` and
|
|
`-XX:MaxHeapFreeRatio`, the G1 garbage collector adjusts the Java heap
|
|
size during the Remark phase, keeping the number of free regions
|
|
within these bounds.
|
|
|
|
In earlier OpenJDK releases, Eden regions were considered to be
|
|
occupied or full for this calculation. This made the heap size
|
|
dependent on the Eden occupancy at the time the Remark phase was
|
|
run. However, after the next garbage collection, these Eden regions
|
|
would be empty.
|
|
|
|
With this OpenJDK release, Eden regions are now considered empty or
|
|
free during the Remark phase calculation. The overall effect is that
|
|
G1 now expands the Java heap less aggressively and more
|
|
determinstically, as the number of free regions does not vary as much.
|
|
It also aligns Java heap sizing with the full GC heap sizing.
|
|
However, this may potentially lead to more garbage collections.
|
|
|
|
JDK-8315503: G1: Code root scan causes long GC pauses due to imbalanced iteration
|
|
=================================================================================
|
|
The Code Root Scan phase of garbage collection finds references to
|
|
Java objects within compiled code. To speed up this process, a cache
|
|
is maintained within each region of the compiled code that contains
|
|
references into the Java heap.
|
|
|
|
On the assumption that the set of references was small, previous
|
|
releases used a single thread per region to iterate through these
|
|
references. This introduced a scalability bottleneck, where
|
|
performance could be reduced if a particular region contained a large
|
|
number of references.
|
|
|
|
In this release, multiple threads are used, removing this bottleneck.
|

Notes on individual issues:

|
tools/javac:
|
|
|
|
JDK-8317300: Align `javac` with the Java Language Specification by Rejecting `final` in Record Patterns
|
|
=======================================================================================================
|
|
Java 21 enhanced the language with pattern matching for switch
|
|
statements. However, the javac compiler released with OpenJDK 21
|
|
allowed the 'final' keyword to be used in front of a record pattern
|
|
(e.g. `case final R(...) ->`), which is a violation of the Java
|
|
Language specification.
|
|
|
|
With this release of OpenJDK 21, programs using `final` within a
|
|
switch statement will now fail to compile. The erroneous keyword will
|
|
need to be removed to allow the program to be compiled.

|
|
JDK-8319124: Update XML Security for Java to 3.0.3
|
|
==================================================
|
|
The XML signature implementation in OpenJDK 21 has been updated to
|
|
Apache Santuario 3.0.3. This update introduces four new SHA-3 based
|
|
RSA-MGF1 SignatureMethod algorithms.
|
|
|
|
However, the API of javax.xml.crypto.dsig.SignatureMethod can not be
|
|
changed in update releases to provide constants for these new
|
|
algorithms. The equivalent string literals should be used as below:
|
|
|
|
* SHA3_224_RSA_MGF1: "http://www.w3.org/2007/05/xmldsig-more#sha3-224-rsa-MGF1"
|
|
* SHA3_256_RSA_MGF1: "http://www.w3.org/2007/05/xmldsig-more#sha3-256-rsa-MGF1"
|
|
* SHA3_384_RSA_MGF1: "http://www.w3.org/2007/05/xmldsig-more#sha3-384-rsa-MGF1"
|
|
* SHA3_512_RSA_MGF1: "http://www.w3.org/2007/05/xmldsig-more#sha3-512-rsa-MGF1"

hotspot/runtime:

|
|
JDK-8325496: Make TrimNativeHeapInterval a product switch
|
|
=========================================================
|
|
The option '-XX:TrimNativeHeapInterval=ms', where 'ms' is the interval
|
|
in milliseconds, is now an official product switch. It allows the
|
|
virtual machine to trim the native heap at the specified interval on
|
|
supported platforms (currently only Linux with glibc). A value of
|
|
zero (the default) disables trimming.

|
|
JDK-8322750: AWT SystemTray API Is Not Supported on Most Linux Desktops
|
|
=======================================================================
|
|
The java.awt.SystemTray API is used to interact with the system's
|
|
desktop taskbar to provide notifications and may include an icon
|
|
representing an application. The GNOME desktop's support for taskbar
|
|
icons has not worked properly for several years, due to a platform
|
|
bug. This bug, in turn, affects the JDK's SystemTray support on GNOME
|
|
desktops.
|
|
|
|
Therefore, in accordance with the SystemTray API specification,
|
|
java.awt.SystemTray.isSupported() will now return false on systems
|
|
that exhibit this bug, which is assumed to be those running a version

|
|
|
The impact of this change is likely to be minimal, as users of the
|
|
SystemTray API should already be able to handle isSupported()
|
|
returning false and the system tray on such platforms has already been
|
|
unsupported for a number of years for all applications.

JDK-8310031: Parallel: Precise Parallel Scanning of Large Object Arrays for Young Collection Roots
|
|
==================================================================================================
|
|
During the collection of young generation objects, the ParallelGC
|
|
collector partitions the old generation into 64kB stripes to scan for
|
|
references to the young generation. The stripes are assigned to worker
|
|
threads to do the scanning in parallel.
|
|
|
|
However, previous releases of OpenJDK 21 did not constrain these
|
|
worker threads to their own stripe. Parallelism was limited as a
|
|
single thread could end up scanning a large object with thousands of
|
|
references across multiple stripes, if it happened to start in its
|
|
allocated stripe. This also resulted in bad scaling, due to the
|
|
subsequent memory sharing associated with multiple threads working on
|
|
the same stripe.
|
|
|
|
In this release, workers are limited to their stripe and only process
|
|
interesting parts of large object arrays. Pauses for the ParallelGC
|
|
collector are now on par with the G1 collector when large object
|
|
arrays are present, reducing pause times by four to five times in some
|
|
cases.

JDK-8325074: ZGC fails assert(index == 0 || is_power_of_2(index)) failed: Incorrect load shift: 11
|
|
==================================================================================================
|
|
Running the virtual machine with `-XX:+UseZGC` and a non-default value
|
|
of `-XX:ObjectAlignmentInBytes` had the potential to crash or perform
|
|
incorrect execution. This was due to `ZBarrierSet::clone_obj_array`
|
|
not taking into account padding words at the end of an ObjArray. This
|
|
has now been rectified in this release.
|
|
|
|
New in release OpenJDK 21.0.2 (2024-01-16):

Notes on individual issues:
|
|
===========================
|
|
|
|
core-libs/java.net:
|
|
|
|
JDK-8308593: Add KEEPALIVE Extended Socket Options Support for Windows
|
|
======================================================================
|
|
On Windows 10 version 1709 and above, TCP_KEEPIDLE and
|
|
TCP_KEEPINTERVAL are now supported in the
|
|
java.net.ExtendedSocketOptions class. Similarly, on Windows 10
|
|
version 1703 and above, TCP_KEEPCOUNT is now supported.
|
|
|
|
hotspot/compiler:
|
|
|
|
JDK-8315082: [REDO] Generational ZGC: Tests crash with assert(index == 0 || is_power_of_2(index))
|
|
=================================================================================================
|
|
In the initial release of JDK 21, running the JVM with -XX:+UseZGC and
|
|
a non-default value of -XX:ObjectAlignmentInBytes could lead to JVM
|
|
crashes or incorrect execution. This issue should now be resolved and
|
|
it should be possible to use these options again.
|
|
|
|
hotspot/runtime:
|
|
|
|
JDK-8317772: NMT: Make peak values available in release builds
|
|
==============================================================
|
|
The peak value is the highest value for committed memory in a given
|
|
Native Memory Tracking (NMT) category over the lifetime of the JVM
|
|
process. NMT reports will now show the peak value for all categories.
|
|
|
|
If the committed memory for a category is at its peak, NMT will
|
|
print "at peak". Otherwise, it prints the peak value.
|
|
|
|
For example, "Compiler (arena=196KB #4) (peak=6126KB #16)" shows that
|
|
compiler arena memory peaked above 6 MB, but now hovers around 200KB.
|
|
|
|
JDK-8313782: Add user-facing warning if THPs are enabled but cannot be used
|
|
===========================================================================
|
|
On Linux, the JVM will now print the following message to standard
|
|
output if Transparent Huge Pages (THPs) are requested, but are not
|
|
supported on the operating system:
|
|
|
|
"UseTransparentHugePages disabled; transparent huge pages are not
|
|
supported by the operating system."

core-libs/java.util.jar:
|
|
|
|
JDK-8313765: Invalid CEN header (invalid zip64 extra data field size)
|
|
=====================================================================
|
|
Additional validity checks in the handling of Zip64 files,
|
|
JDK-8302483, introduced in 21.0.0, caused the use of some valid zip
|
|
files to now fail with the error, `Invalid CEN header (invalid zip64
|
|
extra data field size)`
|
|
|
|
This release, 21.0.1, allows for zero length headers and additional
|
|
padding produced by some Zip64 creation tools.
|
|
|
|
The following third party tools have also released patches to better
|
|
adhere to the ZIP File Format Specification:
|
|
|
|
* Apache Commons Compress fix for Empty CEN Zip64 Extra Headers fixed in Commons Compress release 1.11
|
|
* Apache Ant fix for Empty CEN Zip64 Extra Headers fixed in Ant 1.10.14
|
|
* BND issue with writing invalid Extra Headers fixed in BND 5.3
|
|
|
|
The maven-bundle-plugin 5.1.5 includes the BND 5.3 patch.
|
|
|
|
If these improved validation checks cause issues for deployed zip or
|
|
jar files, check how the file was created and whether patches are
|
|
available from the generating software to resolve the issue. With
|
|
both JDK releases, the checks can be disabled by setting the new
|
|
system property, `jdk.util.zip.disableZip64ExtraFieldValidation` to
|
|
`true`.

|
JDK-8311981: JVM May Hang When Using Generational ZGC if a VM Handshake Stalls on Memory
|
|
========================================================================================
|
|
The JVM can hang under an uncommon condition that involves the JVM
|
|
running out of heap memory, the GC just starting a relocation phase to
|
|
reclaim memory, and a JVM thread-local Handshake asking to relocate an
|
|
object. This potential deadlock should now be avoided in this
|
|
release.
|
|
|
|
core-libs/java.util.regex:
|
|
|
|
JDK-8312976: `java.util.regex.MatchResult` Might Throw `StringIndexOutOfBoundsException` on Regex Patterns Containing Lookaheads and Lookbehinds
|
|
================================================================================================================================================
|
|
JDK-8132995 introduced an unintended regression when using instances
|
|
returned by `java.util.regex.Matcher.toMatchResult()`.
|
|
|
|
This regression happens with a `java.util.regex.Pattern`s containing
|
|
lookaheads and lookbehinds that, in turn, contain groups. If these are
|
|
located outside the match, a `StringIndexOutOfBoundsException` is
|
|
thrown when accessing these groups. See JDK-8312976 for an example.
|
|
|
|
The issue is resolved in this release by calculating a minimum start
|
|
location as part of the match result and using this in constructing
|
|
String objects, rather than the location of the first match.
|
|
|
|
JDK-8314960: Added Certigna Root CA Certificate
|
|
===============================================
|
|
The following root certificate has been added to the cacerts
|
|
truststore:
|
|
|
|
Name: Certigna (Dhimyotis)
|
|
Alias Name: certignarootca
|
|
Distinguished Name: CN=Certigna Root CA, OU=0002 48146308100036, O=Dhimyotis, C=FR
|
|
|
|
JDK-8312489: Increase Default Value of the System Property `jdk.jar.maxSignatureFileSize`
|
|
=========================================================================================
|
|
A maximum signature file size property, jdk.jar.maxSignatureFileSize,
|
|
was introduced in the 21.0.0 release of OpenJDK by JDK-8300596 to
|
|
control the maximum size of signature files in a signed JAR. The
|
|
default value of 8MB proved to be too small for some JAR files. This
|
|
release, 21.0.1, increases it to 16MB.
|
|
|
|
New in release OpenJDK 21.0.0 (2023-09-XX):
|
|
===========================================
|
|
Major changes are listed below. Some changes may have been backported
|
|
to earlier releases following their first appearance in OpenJDK 18
|
|
through to 21.
|
|
|
|
NEW FEATURES
|
|
============
|
|
|
|
Language Features
|
|
=================
|
|
|
|
Pattern Matching for switch
|
|
===========================
|
|
https://openjdk.org/jeps/406
|
|
https://openjdk.org/jeps/420
|
|
https://openjdk.org/jeps/427
|
|
https://openjdk.org/jeps/433
|
|
https://openjdk.org/jeps/441
|
|
|
|
Enhance the Java programming language with pattern matching for
|
|
`switch` expressions and statements, along with extensions to the
|
|
language of patterns. Extending pattern matching to `switch` allows an
|
|
expression to be tested against a number of patterns, each with a
|
|
specific action, so that complex data-oriented queries can be
|
|
expressed concisely and safely.
|
|
|
|
This was a preview feature (http://openjdk.java.net/jeps/12)
|
|
introduced in OpenJDK 17 (JEP 406), which saw a second preview in
|
|
OpenJDK 18 (JEP 420), a third in OpenJDK 19 (JEP 427) and a fourth
|
|
(JEP 427) in OpenJDK 20. It became final with OpenJDK 21 (JEP 441).
|
|
|
|
Record Patterns
|
|
===============
|
|
https://openjdk.org/jeps/405
|
|
https://openjdk.org/jeps/432
|
|
https://openjdk.org/jeps/440
|
|
|
|
Enhance the Java programming language with record patterns to
|
|
deconstruct record values. Record patterns and type patterns can be
|
|
nested to enable a powerful, declarative, and composable form of data
|
|
navigation and processing.
|
|
|
|
This was a preview feature (http://openjdk.java.net/jeps/12) introduced
|
|
in OpenJDK 19 (JEP 405) with a second preview (JEP 432) in OpenJDK 20.
|
|
It became final with OpenJDK 21 (JEP 440).
|
|
|
|
String Templates
|
|
================
|
|
https://openjdk.org/jeps/430
|
|
|
|
Enhance the Java programming language with string templates. String
|
|
templates complement Java's existing string literals and text blocks
|
|
by coupling literal text with embedded expressions and template
|
|
processors to produce specialized results.
|
|
|
|
This is a preview feature (http://openjdk.java.net/jeps/12) introduced
|
|
in OpenJDK 21 (JEP 430).
|
|
|
|
Unnamed Patterns and Variables
|
|
==============================
|
|
https://openjdk.org/jeps/443
|
|
|
|
Enhance the Java language with unnamed patterns, which match a record
|
|
component without stating the component's name or type, and unnamed
|
|
variables, which can be initialized but not used. Both are denoted by
|
|
an underscore character, _.
|
|
|
|
This is a preview feature (http://openjdk.java.net/jeps/12) introduced
|
|
in OpenJDK 21 (JEP 443).
|
|
|
|
Unnamed Classes and Instance Main Methods (Preview)
|
|
===================================================
|
|
https://openjdk.org/jeps/445
|
|
|
|
Evolve the Java language so that students can write their first
|
|
programs without needing to understand language features designed for
|
|
large programs. Far from using a separate dialect of Java, students
|
|
can write streamlined declarations for single-class programs and then
|
|
seamlessly expand their programs to use more advanced features as
|
|
their skills grow.
|
|
|
|
This is a preview feature (http://openjdk.java.net/jeps/12) introduced
|
|
in OpenJDK 21 (JEP 445).
|
|
|
|
Library Features
|
|
================
|
|
|
|
UTF-8 by Default
|
|
================
|
|
https://openjdk.org/jeps/400
|
|
|
|
Specify UTF-8 as the default charset of the standard Java APIs. With
|
|
this change, APIs that depend upon the default charset will behave
|
|
consistently across all implementations, operating systems, locales,
|
|
and configurations.
|
|
|
|
Reimplement Core Reflection with Method Handles
|
|
===============================================
|
|
https://openjdk.org/jeps/416
|
|
|
|
Reimplement java.lang.reflect.Method, Constructor, and Field on top of
|
|
java.lang.invoke method handles. Making method handles the underlying
|
|
mechanism for reflection will reduce the maintenance and development
|
|
cost of both the java.lang.reflect and java.lang.invoke APIs.
|
|
|
|
Vector API
|
|
==========
|
|
https://openjdk.org/jeps/338
|
|
https://openjdk.org/jeps/414
|
|
https://openjdk.org/jeps/417
|
|
https://openjdk.org/jeps/426
|
|
https://openjdk.org/jeps/438
|
|
https://openjdk.org/jeps/448
|
|
|
|
Introduce an API to express vector computations that reliably compile
|
|
at runtime to optimal vector hardware instructions on supported CPU
|
|
architectures and thus achieve superior performance to equivalent
|
|
scalar computations.
|
|
|
|
This is an incubation feature (https://openjdk.java.net/jeps/11)
|
|
introduced in OpenJDK 16 (JEP 338). A second round of incubation took
|
|
place in OpenJDK 17 (JEP 414), OpenJDK 18 (JEP 417) saw a third,
|
|
OpenJDK 19 a fourth (JEP 426), OpenJDK 20 (JEP 438) a fifth and
|
|
OpenJDK 21 a sixth (JEP 448).
|
|
|
|
Internet-Address Resolution SPI
|
|
===============================
|
|
https://openjdk.org/jeps/418
|
|
|
|
Define a service-provider interface (SPI) for host name and address
|
|
resolution, so that java.net.InetAddress can make use of resolvers
|
|
other than the platform's built-in resolver.
|
|
|
|
Foreign Function & Memory API
|
|
=============================
|
|
https://openjdk.org/jeps/412
|
|
https://openjdk.org/jeps/419
|
|
https://openjdk.org/jeps/424
|
|
https://openjdk.org/jeps/434
|
|
https://openjdk.org/jeps/442
|
|
|
|
Introduce an API by which Java programs can interoperate with code and
|
|
data outside of the Java runtime. By efficiently invoking foreign
|
|
functions (i.e., code outside the JVM), and by safely accessing
|
|
foreign memory (i.e., memory not managed by the JVM), the API enables
|
|
Java programs to call native libraries and process native data without
|
|
the brittleness and danger of JNI.
|
|
|
|
This API is now a preview feature (http://openjdk.java.net/jeps/12).
|
|
It was first introduced in incubation
|
|
(https://openjdk.java.net/jeps/11) in OpenJDK 17 (JEP 412), and is an
|
|
evolution of the Foreign Memory Access API (OpenJDK 14 through 16) and
|
|
Foreign Linker API (OpenJDK 16) (see release notes for
|
|
java-17-openjdk). OpenJDK 18 saw a second round of incubation (JEP
|
|
419) before its inclusion as a preview in OpenJDK 19 (JEP 424) and a
|
|
second in OpenJDK 20 (JEP 434). It reaches a third preview in OpenJDK
|
|
21 (JEP 442).
|
|
|
|
Virtual Threads
|
|
===============
|
|
https://openjdk.org/jeps/425
|
|
https://openjdk.org/jeps/436
|
|
https://openjdk.org/jeps/444
|
|
|
|
Introduce virtual threads to the Java Platform. Virtual threads are
|
|
lightweight threads that dramatically reduce the effort of writing,
|
|
maintaining, and observing high-throughput concurrent applications.
|
|
|
|
This was a preview feature (http://openjdk.java.net/jeps/12)
|
|
introduced in OpenJDK 19 (JEP 425) and reaching its second preview in
|
|
OpenJDK 20 (JEP 436). It became final with OpenJDK 21 (JEP 444).
|
|
|
|
Structured Concurrency
|
|
======================
|
|
https://openjdk.org/jeps/428
|
|
https://openjdk.org/jeps/437
|
|
https://openjdk.org/jeps/453
|
|
|
|
Simplify multithreaded programming by introducing an API for
|
|
structured concurrency. Structured concurrency treats multiple tasks
|
|
running in different threads as a single unit of work, thereby
|
|
streamlining error handling and cancellation, improving reliability,
|
|
and enhancing observability.
|
|
|
|
This API is now a preview feature (http://openjdk.java.net/jeps/12) in
|
|
OpenJDK 21 (JEP 453). It was first introduced in incubation
|
|
(https://openjdk.java.net/jeps/11) in OpenJDK 19 (JEP 428) and had a
|
|
second round of incubation in OpenJDK 20 (JEP 437).
|
|
|
|
Scoped Values
|
|
=============
|
|
https://openjdk.org/jeps/429
|
|
|
|
Introduce scoped values, which enable the sharing of immutable data
|
|
within and across threads. They are preferred to thread-local
|
|
variables, especially when using large numbers of virtual threads.
|
|
|
|
This API is now a preview feature (http://openjdk.java.net/jeps/12)
|
|
in OpenJDK 21 (JEP 429). It was first introduced in incubation
|
|
(https://openjdk.java.net/jeps/11) in OpenJDK 20 (JEP 429).
|
|
|
|
Sequenced Collections
|
|
=====================
|
|
https://openjdk.org/jeps/431
|
|
|
|
Introduce new interfaces to represent collections with a defined
|
|
encounter order. Each such collection has a well-defined first
|
|
element, second element, and so forth, up to the last element. It also
|
|
provides uniform APIs for accessing its first and last elements, and
|
|
for processing its elements in reverse order.
|
|
|
|
Key Encapsulation Mechanism API
|
|
===============================
|
|
https://openjdk.org/jeps/452
|
|
|
|
Introduce an API for key encapsulation mechanisms (KEMs), an
|
|
encryption technique for securing symmetric keys using public key
|
|
cryptography.
|
|
|
|
Virtual Machine Enhancements
|
|
============================
|
|
|
|
Generational ZGC
|
|
================
|
|
https://openjdk.org/jeps/439
|
|
|
|
Improve application performance by extending the Z Garbage Collector
|
|
(ZGC) to maintain separate generations for young and old objects. This
|
|
will allow ZGC to collect young objects — which tend to die young —
|
|
more frequently.
|
|
|
|
Tools
|
|
=====
|
|
|
|
Simple Web Server
|
|
=================
|
|
https://openjdk.org/jeps/408
|
|
|
|
Provide a command-line tool, `jwebserver`, to start a minimal web
|
|
server that serves static files only. No CGI or servlet-like
|
|
functionality is available. This tool will be useful for prototyping,
|
|
ad-hoc coding, and testing purposes, particularly in educational
|
|
contexts.
|
|
|
|
Code Snippets in Java API Documentation
|
|
=======================================
|
|
https://openjdk.org/jeps/413
|
|
|
|
Introduce an @snippet tag for JavaDoc's Standard Doclet, to simplify
|
|
the inclusion of example source code in API documentation.
|
|
|
|
Ports
|
|
=====
|
|
|
|
Linux/RISC-V Port
|
|
=================
|
|
https://openjdk.org/jeps/422
|
|
|
|
RISC-V is a free and open-source RISC instruction set architecture
|
|
(ISA) designed originally at the University of California, Berkeley,
|
|
and now developed collaboratively under the sponsorship of RISC-V
|
|
International. It is already supported by a wide range of language
|
|
toolchains. With the increasing availability of RISC-V hardware, a
|
|
port of the JDK would be valuable.
|
|
|
|
DEPRECATIONS
|
|
============
|
|
|
|
Deprecate Finalization for Removal
|
|
==================================
|
|
https://openjdk.org/jeps/421
|
|
|
|
Deprecate finalization for removal in a future release. Finalization
|
|
remains enabled by default for now, but can be disabled to facilitate
|
|
early testing. In a future release it will be disabled by default, and
|
|
in a later release it will be removed. Maintainers of libraries and
|
|
applications that rely upon finalization should consider migrating to
|
|
other resource management techniques such as the try-with-resources
|
|
statement and cleaners.
|
|
|
|
Deprecate the Windows 32-bit x86 Port for Removal
|
|
=================================================
|
|
https://openjdk.org/jeps/449
|
|
|
|
Deprecate the Windows 32-bit x86 port, with the intent to remove it in
|
|
a future release.
|
|
|
|
Prepare to Disallow the Dynamic Loading of Agents
|
|
=================================================
|
|
https://openjdk.org/jeps/451
|
|
|
|
Issue warnings when agents are loaded dynamically into a running
|
|
JVM. These warnings aim to prepare users for a future release which
|
|
disallows the dynamic loading of agents by default in order to improve
|
|
integrity by default. Serviceability tools that load agents at startup
|
|
will not cause warnings to be issued in any release.
|
