Notes on individual issues:
|
||||
NEW FEATURES
|
||||
============
|
||||
|
||||
Language Features
|
||||
=================
|
||||
|
||||
Switch Expressions
|
||||
==================
|
||||
https://openjdk.java.net/jeps/325
|
||||
https://openjdk.java.net/jeps/354
|
||||
https://openjdk.java.net/jeps/361
|
||||
|
||||
Extend the `switch` statement so that it can be used as either a
|
||||
statement or an expression, and that both forms can use either a
|
||||
"traditional" or "simplified" scoping and control flow behavior. Both
|
||||
forms can use either traditional `case ... :` labels (with fall
|
||||
through) or new `case ... ->` labels (with no fall through), with a
|
||||
further new statement for yielding a value from a `switch`
|
||||
expression. These changes will simplify everyday coding, and also
|
||||
prepare the way for the use of pattern matching in `switch`.
|
||||
|
||||
This was a preview feature (http://openjdk.java.net/jeps/12) in
|
||||
OpenJDK 12 & 13 and became final in OpenJDK 14.
|
||||
|
||||
Text Blocks
|
||||
===========
|
||||
https://openjdk.java.net/jeps/355
|
||||
https://openjdk.java.net/jeps/368
|
||||
https://openjdk.java.net/jeps/378
|
||||
|
||||
Add text blocks to the Java language. A text block is a multi-line
|
||||
string literal that avoids the need for most escape sequences,
|
||||
automatically formats the string in a predictable way, and gives the
|
||||
developer control over format when desired.
|
||||
|
||||
This was a preview feature (http://openjdk.java.net/jeps/12) in
|
||||
OpenJDK 13 & 14 and became final in OpenJDK 15.
|
||||
|
||||
Pattern Matching for instanceof
|
||||
===============================
|
||||
https://openjdk.java.net/jeps/305
|
||||
https://openjdk.java.net/jeps/375
|
||||
https://openjdk.java.net/jeps/394
|
||||
http://cr.openjdk.java.net/~briangoetz/amber/pattern-match.html
|
||||
|
||||
Enhance the Java programming language with pattern matching for the
|
||||
`instanceof` operator. Pattern matching allows common logic in a
|
||||
program, namely the conditional extraction of components from objects,
|
||||
to be expressed more concisely and safely.
|
||||
|
||||
This was a preview feature (http://openjdk.java.net/jeps/12) in
|
||||
OpenJDK 14 & 15 and became final in OpenJDK 16.
|
||||
|
||||
Records
|
||||
=======
|
||||
https://openjdk.java.net/jeps/359
|
||||
https://openjdk.java.net/jeps/384
|
||||
https://openjdk.java.net/jeps/395
|
||||
|
||||
Enhance the Java programming language with records. Records provide a
|
||||
compact syntax for declaring classes which are transparent holders for
|
||||
shallowly immutable data.
|
||||
|
||||
This was a preview feature (http://openjdk.java.net/jeps/12) in
|
||||
OpenJDK 14 & 15 and became final in OpenJDK 16.
|
||||
|
||||
Sealed Classes
|
||||
==============
|
||||
https://openjdk.java.net/jeps/360
|
||||
https://openjdk.java.net/jeps/397
|
||||
https://openjdk.java.net/jeps/409
|
||||
https://cr.openjdk.java.net/~briangoetz/amber/datum.html
|
||||
|
||||
Enhance the Java programming language with sealed classes and
|
||||
interfaces. Sealed classes and interfaces restrict which other classes
|
||||
or interfaces may extend or implement them.
|
||||
|
||||
This was a preview feature (http://openjdk.java.net/jeps/12) in
|
||||
OpenJDK 15 & 16 and became final in OpenJDK 17.
|
||||
|
||||
Restore Always-Strict Floating-Point Semantics
|
||||
==============================================
|
||||
https://openjdk.java.net/jeps/306
|
||||
|
||||
Make floating-point operations consistently strict, rather than have
|
||||
both strict floating-point semantics (`strictfp`) and subtly different
|
||||
default floating-point semantics. This will restore the original
|
||||
floating-point semantics to the language and VM, matching the
|
||||
semantics before the introduction of strict and default floating-point
|
||||
modes in Java SE 1.2.
|
||||
|
||||
Pattern Matching for switch
|
||||
===========================
|
||||
https://openjdk.java.net/jeps/406
|
||||
|
||||
core-libs/java.time:
|
||||
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.
|
||||
|
||||
JDK-8254177: US/Pacific-New Zone name removed as part of tzdata2020b
|
||||
====================================================================
|
||||
Following JDK's update to tzdata2020b, the long-obsolete files
|
||||
pacificnew and systemv have been removed. As a result, the
|
||||
"US/Pacific-New" zone name declared in the pacificnew data file is no
|
||||
longer available for use.
|
||||
This is a preview feature (http://openjdk.java.net/jeps/12) in OpenJDK
|
||||
17.
|
||||
|
||||
Information regarding the update can be viewed at
|
||||

|
||||
constant pool.
|
||||
|
||||
Notes on individual issues:
|
||||
Reimplement the Legacy Socket API
|
||||
=================================
|
||||
https://openjdk.java.net/jeps/353
|
||||
|
||||
Replace the underlying implementation used by the `java.net.Socket`
|
||||
and `java.net.ServerSocket` APIs with a simpler and more modern
|
||||
implementation that is easy to maintain and debug. The new
|
||||
implementation will be easy to adapt to work with user-mode threads,
|
||||
a.k.a. fibers, currently being explored in Project Loom
|
||||
(https://openjdk.java.net/projects/loom).
|
||||
|
||||
JFR Event Streaming
|
||||
===================
|
||||
https://openjdk.java.net/jeps/349
|
||||
|
||||
Expose JDK Flight Recorder data for continuous monitoring.
|
||||
|
||||
Non-Volatile Mapped Byte Buffers
|
||||
================================
|
||||
https://openjdk.java.net/jeps/352
|
||||
|
||||
Add new JDK-specific file mapping modes so that the `FileChannel` API
|
||||
can be used to create `MappedByteBuffer` instances that refer to
|
||||
non-volatile memory.
|
||||
|
||||
Helpful NullPointerExceptions
|
||||
=============================
|
||||
https://openjdk.java.net/jeps/358
|
||||
|
||||
Improve the usability of `NullPointerException`s generated by the JVM
|
||||
by describing precisely which variable was `null`.
|
||||
|
||||
Foreign-Memory Access API
|
||||
=========================
|
||||
https://openjdk.java.net/jeps/370
|
||||
https://openjdk.java.net/jeps/383
|
||||
https://openjdk.java.net/jeps/393
|
||||
|
||||
Introduce an API to allow Java programs to safely and efficiently
|
||||
access foreign memory outside of the Java heap.
|
||||
|
||||
This was a incubation feature (https://openjdk.java.net/jeps/11) in
|
||||
OpenJDK 14, 15 & 16, now superseded by the Foreign Function & Memory
|
||||
API in OpenJDK 17 (see below).
|
||||
|
||||
Edwards-Curve Digital Signature Algorithm (EdDSA)
|
||||
=================================================
|
||||
https://openjdk.java.net/jeps/339
|
||||
|
||||
Implement cryptographic signatures using the Edwards-Curve Digital
|
||||
Signature Algorithm (EdDSA) as described by RFC 8032
|
||||
(https://tools.ietf.org/html/rfc8032).
|
||||
|
||||
Hidden Classes
|
||||
==============
|
||||
https://openjdk.java.net/jeps/371
|
||||
|
||||
Introduce hidden classes, which are classes that cannot be used
|
||||
directly by the bytecode of other classes. Hidden classes are intended
|
||||
for use by frameworks that generate classes at run time and use them
|
||||
indirectly, via reflection. A hidden class may be defined as a member
|
||||
of an access control nest (https://openjdk.java.net/jeps/181), and may
|
||||
be unloaded independently of other classes.
|
||||
|
||||
Reimplement the Legacy DatagramSocket API
|
||||
=========================================
|
||||
https://openjdk.java.net/jeps/373
|
||||
|
||||
Replace the underlying implementations of the
|
||||
`java.net.DatagramSocket` and `java.net.MulticastSocket` APIs with
|
||||
simpler and more modern implementations that are easy to maintain and
|
||||
debug. The new implementations will be easy to adapt to work with
|
||||
virtual threads, currently being explored in Project Loom
|
||||
(https://openjdk.java.net/projects/loom). This is a follow-on to JEP
|
||||
353 (see above), which already reimplemented the legacy Socket API.
|
||||
|
||||
Vector API
|
||||
==========
|
||||
https://openjdk.java.net/jeps/338
|
||||
https://openjdk.java.net/jeps/414
|
||||
|
||||
Provide an initial iteration of an incubator module,
|
||||
`jdk.incubator.vector`, 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.
|
||||
|
||||
Unix-Domain Socket Channels
|
||||
===========================
|
||||
https://openjdk.java.net/jeps/380
|
||||
|
||||
security-libs/java.security:
|
||||
Add Unix-domain (`AF_UNIX`) socket support to the socket channel and
|
||||
server-socket channel APIs in the `java.nio.channels` package. Extend
|
||||
the inherited channel mechanism to support Unix-domain socket channels
|
||||
and server socket channels.
|
||||
|
||||
JDK-8250756: Added Entrust Root Certification Authority - G4 certificate
|
||||
========================================================================
|
||||
The Entrust root certificate has been added to the cacerts truststore:
|
||||
Foreign Linker API (Incubator)
|
||||
==============================
|
||||
https://openjdk.java.net/jeps/389
|
||||
|
||||
Alias Name: entrustrootcag4
|
||||
Distinguished Name: CN=Entrust Root Certification Authority - G4, OU="(c) 2015 Entrust, Inc. - for authorized use only", OU=See www.entrust.net/legal-terms, O="Entrust, Inc.", C=US
|
||||
Introduce an API that offers statically-typed, pure-Java access to
|
||||
native code. This API, together with the Foreign-Memory API (see
|
||||
above), will considerably simplify the otherwise error-prone process
|
||||
of binding to a native library.
|
||||
|
||||
JDK-8250860: Added 3 SSL Corporation Root CA Certificates
|
||||
This was an incubation feature (https://openjdk.java.net/jeps/11)
|
||||
introduced in OpenJDK 16, now superseded by the Foreign Function &
|
||||
Memory API in OpenJDK 17 (see below).
|
||||
|
||||
Strongly Encapsulate JDK Internals by Default
|
||||
=============================================
|
||||
https://openjdk.java.net/jeps/396
|
||||
https://openjdk.java.net/jeps/403
|
||||
|
||||
Strongly encapsulate all internal elements of the JDK by default,
|
||||
except for critical internal APIs such as `sun.misc.Unsafe`. It will
|
||||
no longer be possible to relax the strong encapsulation of internal
|
||||
elements via a single command-line option, as was possible in OpenJDK
|
||||
9 through 16.
|
||||
|
||||
Enhanced Pseudo-Random Number Generators
|
||||
========================================
|
||||
https://openjdk.java.net/jeps/356
|
||||
|
||||
Provide new interface types and implementations for pseudo-random
|
||||
number generators (PRNGs), including jumpable PRNGs and an additional
|
||||
class of splittable PRNG algorithms (LXM).
|
||||
|
||||
Foreign Function & Memory API
|
||||
=============================
|
||||
https://openjdk.java.net/jeps/412
|
||||
|
||||
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 an incubation feature (https://openjdk.java.net/jeps/11)
|
||||
introduced in OpenJDK 17, and is an evolution of the Foreign Memory
|
||||
Access API (OpenJDK 14 through 16) and Foreign Linker API (OpenJDK
|
||||
16) (see above).
|
||||
|
||||
Context-Specific Deserialization Filters
|
||||
========================================
|
||||
https://openjdk.java.net/jeps/415
|
||||
|
||||
Allow applications to configure context-specific and
|
||||
dynamically-selected deserialization filters via a JVM-wide filter
|
||||
factory that is invoked to select a filter for each individual
|
||||
deserialization operation.
|
||||
|
||||
Tools
|
||||
=====
|
||||
|
||||
Packaging Tool
|
||||
==============
|
||||
https://openjdk.java.net/jeps/343
|
||||
https://openjdk.java.net/jeps/392
|
||||
|
||||
Provide the `jpackage` tool, for packaging self-contained Java
|
||||
applications.
|
||||
|
||||
JVM Features
|
||||
============
|
||||
|
||||
Shenandoah: A Low-Pause-Time Garbage Collector
|
||||
==============================================
|
||||
https://openjdk.java.net/jeps/189
|
||||
https://openjdk.java.net/jeps/379
|
||||
|
||||
Add a new garbage collection (GC) algorithm named Shenandoah which
|
||||
reduces GC pause times by doing evacuation work concurrently with the
|
||||
running Java threads. Pause times with Shenandoah are independent of
|
||||
heap size, meaning you will have the same consistent pause times
|
||||
whether your heap is 200 MB or 200 GB.
|
||||
|
||||
Shenandoah has been provided in Red Hat builds of OpenJDK 8 since
|
||||
8u131 in April 2017 and in all 11u builds.
|
||||
|
||||
Upstream, it was introduced in OpenJDK 12 as an experimental feature
|
||||
and became a production feature in OpenJDK 15. It was backported to
|
||||
OpenJDK 11 with the 11.0.9 release in October 2020.
|
||||
|
||||
Abortable Mixed Collections for G1
|
||||
==================================
|
||||
https://openjdk.java.net/jeps/344
|
||||
|
||||
Make G1 mixed collections abortable if they might exceed the pause
|
||||
target.
|
||||
|
||||
Promptly Return Unused Committed Memory from G1
|
||||
===============================================
|
||||
https://openjdk.java.net/jeps/346
|
||||
|
||||
Enhance the G1 garbage collector to automatically return Java heap
|
||||
memory to the operating system when idle.
|
||||
|
||||
Dynamic CDS Archives
|
||||
====================
|
||||
https://openjdk.java.net/jeps/310
|
||||
https://openjdk.java.net/jeps/350
|
||||
|
||||
Extend application class-data sharing to allow the dynamic archiving
|
||||
of classes at the end of Java application execution. The archived
|
||||
classes will include all loaded application classes and library
|
||||
classes that are not present in the default, base-layer CDS archive.
|
||||
|
||||
ZGC: Uncommit Unused Memory (Experimental)
|
||||
==========================================
|
||||
https://openjdk.java.net/jeps/351
|
||||
|
||||
Enhance ZGC to return unused heap memory to the operating system.
|
||||
|
||||
NUMA-Aware Memory Allocation for G1
|
||||
===================================
|
||||
https://openjdk.java.net/jeps/345
|
||||
|
||||
Improve G1 performance on large machines by implementing NUMA-aware
|
||||

|
||||
|
||||
ZGC on Windows (Experimental)
|
||||
=============================
|
||||
https://openjdk.java.net/jeps/365
|
||||
|
||||
Port the ZGC garbage collector to Windows.
|
||||
|
||||
ZGC: A Scalable Low-Latency Garbage Collector (Production)
|
||||
==========================================================
|
||||
https://openjdk.java.net/jeps/377
|
||||
|
||||
Change the Z Garbage Collector from an experimental feature into a
|
||||
product feature.
|
||||
|
||||
ZGC: Concurrent Thread-Stack Processing
|
||||
=======================================
|
||||
https://openjdk.java.net/jeps/376
|
||||
|
||||
Move ZGC thread-stack processing from safepoints to a concurrent
|
||||
phase.
|
||||
|
||||
Elastic Metaspace
|
||||
=================
|
||||
https://openjdk.java.net/jeps/387
|
||||
|
||||
Return unused HotSpot class-metadata (i.e., metaspace) memory to the
|
||||
operating system more promptly, reduce metaspace footprint, and
|
||||
simplify the metaspace code in order to reduce maintenance costs.
|
||||
|
||||
Ports
|
||||
=====
|
||||
|
||||
Alpine Linux Port
|
||||
=================
|
||||
https://openjdk.java.net/jeps/386
|
||||
|
||||
Port the JDK to Alpine Linux, and to other Linux distributions that
|
||||
use musl as their primary C library, on both the x64 and AArch64
|
||||
architectures,
|
||||
|
||||
Windows/AArch64 Port
|
||||
====================
|
||||
https://openjdk.java.net/jeps/388
|
||||
|
||||
Port the JDK to Windows/AArch64.
|
||||
|
||||
New macOS Rendering Pipeline
|
||||
============================
|
||||
https://openjdk.java.net/jeps/382
|
||||
|
||||
Implement a Java 2D internal rendering pipeline for macOS using the
|
||||
Apple Metal API as alternative to the existing pipeline, which uses
|
||||
the deprecated Apple OpenGL API.
|
||||
|
||||
macOS/AArch64 Port
|
||||
==================
|
||||
https://openjdk.java.net/jeps/391
|
||||
|
||||
Port the JDK to macOS/AArch64.
|
||||
|
||||
DEPRECATIONS
|
||||
============
|
||||
|
||||
Deprecate the ParallelScavenge + SerialOld GC Combination
|
||||
=========================================================
|
||||
The following root certificates have been added to the cacerts truststore for the SSL Corporation:
|
||||
https://openjdk.java.net/jeps/366
|
||||
|
||||
Alias Name: sslrootrsaca
|
||||
Distinguished Name: CN=SSL.com Root Certification Authority RSA, O=SSL Corporation, L=Houston, ST=Texas, C=US
|
||||
Deprecate the combination of the Parallel Scavenge and Serial Old
|
||||
garbage collection algorithms.
|
||||
|
||||
Alias Name: sslrootevrsaca
|
||||
Distinguished Name: CN=SSL.com EV Root Certification Authority RSA R2, O=SSL Corporation, L=Houston, ST=Texas, C=US
|
||||
Deprecate and Disable Biased Locking
|
||||
====================================
|
||||
https://openjdk.java.net/jeps/374
|
||||
|
||||
Alias Name: sslrooteccca
|
||||
Distinguished Name: CN=SSL.com Root Certification Authority ECC, O=SSL Corporation, L=Houston, ST=Texas, C=US
|
||||
Disable biased locking by default, and deprecate all related
|
||||
command-line options.
|
||||
|
||||
Warnings for Value-Based Classes
|
||||
================================
|
||||
https://openjdk.java.net/jeps/390
|
||||
|
||||
Designate the primitive wrapper classes as value-based and deprecate
|
||||
their constructors for removal, prompting new deprecation
|
||||
warnings. Provide warnings about improper attempts to synchronize on
|
||||
instances of any value-based classes in the Java Platform.
|
||||
|
||||
Deprecate the Applet API for Removal
|
||||
====================================
|
||||
https://openjdk.java.net/jeps/398
|
||||
|
||||
Deprecate the Applet API for removal. It is essentially irrelevant
|
||||
since all web-browser vendors have either removed support for Java
|
||||
browser plug-ins or announced plans to do so.
|
||||
|
||||
Deprecate the Security Manager for Removal
|
||||
==========================================
|
||||
https://openjdk.java.net/jeps/411
|
||||
|
||||
Deprecate the Security Manager for removal in a future release. The
|
||||
Security Manager dates from Java 1.0. It has not been the primary
|
||||
means of securing client-side Java code for many years, and it has
|
||||
rarely been used to secure server-side code. To move Java forward, we
|
||||
intend to deprecate the Security Manager for removal in concert with
|
||||
the legacy Applet API (see above). .
|
||||
|
||||
REMOVALS
|
||||
========
|
||||
|
||||
Remove the Concurrent Mark Sweep (CMS) Garbage Collector
|
||||
========================================================
|
||||
https://openjdk.java.net/jeps/363
|
||||
|
||||
Remove the Concurrent Mark Sweep (CMS) garbage collector.
|
||||
|
||||
Remove the Pack200 Tools and API
|
||||
================================
|
||||
https://openjdk.java.net/jeps/336
|
||||
https://openjdk.java.net/jeps/367
|
||||
|
||||
Remove the `pack200` and `unpack200` tools, and the `Pack200` API in
|
||||
the `java.util.jar` package. These tools and API were deprecated for
|
||||
removal in OpenJDK 11 with the express intent to remove them in a
|
||||
future release.
|
||||
|
||||
Remove the Nashorn JavaScript Engine
|
||||
====================================
|
||||
https://openjdk.java.net/jeps/372
|
||||
|
||||
Remove the Nashorn JavaScript script engine and APIs, and the `jjs`
|
||||
tool. The engine, the APIs, and the tool were deprecated for removal
|
||||
in OpenJDK 11 with the express intent to remove them in a future
|
||||
release.
|
||||
|
||||
Remove the Solaris and SPARC Ports
|
||||
==================================
|
||||
https://openjdk.java.net/jeps/362
|
||||
https://openjdk.java.net/jeps/381
|
||||
|
||||
Remove the source code and build support for the Solaris/SPARC,
|
||||
Solaris/x64, and Linux/SPARC ports. These ports were deprecated for
|
||||
removal in OpenJDK 14 (JEP 362) and removed in OpenJDK 15 (JEP 381).
|
||||
|
||||
Remove RMI Activation
|
||||
=====================
|
||||
https://openjdk.java.net/jeps/385
|
||||
https://openjdk.java.net/jeps/407
|
||||
https://docs.oracle.com/en/java/javase/14/docs/specs/rmi/activation.html
|
||||
|
||||
Remove the Remote Method Invocation (RMI) Activation mechanism, while
|
||||
preserving the rest of RMI. RMI Activation is an obsolete part of RMI
|
||||
that has been optional since OpenJDK 8 and was deprecated in OpenJDK
|
||||
15.
|
||||
|
||||
Remove the Experimental AOT and JIT Compiler
|
||||
============================================
|
||||
https://openjdk.java.net/jeps/410
|
||||
|
||||
Remove the experimental Java-based ahead-of-time (AOT) and
|
||||
just-in-time (JIT) compiler. This compiler has seen little use since
|
||||
its introduction and the effort required to maintain it is
|
||||
significant. Retain the experimental Java-level JVM compiler
|
||||
interface (JVMCI) so that developers can continue to use
|
||||
externally-built versions of the compiler for JIT compilation.
