Notes on individual issues:
|
|
|
|
|
===========================
|
|
|
|
|
|
|
|
|
|
client-libs/javax.imageio:
|
|
|
|
|
|
|
|
|
|
JDK-8295687: Better BMP bounds
|
|
|
|
|
==============================
|
|
|
|
|
Loading a linked ICC profile within a BMP image is now disabled by
|
|
|
|
|
default. To re-enable it, set the new system property
|
|
|
|
|
`sun.imageio.bmp.enabledLinkedProfiles` to `true`. This new property
|
|
|
|
|
replaces the old property,
|
|
|
|
|
`sun.imageio.plugins.bmp.disableLinkedProfiles`.
|
|
|
|
|
|
|
|
|
|
client-libs/javax.sound:
|
|
|
|
|
|
|
|
|
|
JDK-8293742: Better Banking of Sounds
|
|
|
|
|
=====================================
|
|
|
|
|
Previously, the SoundbankReader implementation,
|
|
|
|
|
`com.sun.media.sound.JARSoundbankReader`, would download a JAR
|
|
|
|
|
soundbank from a URL. This behaviour is now disabled by default. To
|
|
|
|
|
re-enable it, set the new system property `jdk.sound.jarsoundbank` to
|
|
|
|
|
`true`.
|
|
|
|
|
|
|
|
|
|
security-libs/javax.net.ssl:
|
|
|
|
|
|
|
|
|
|
JDK-8287411: Enhance DTLS performance
|
|
|
|
|
=====================================
|
|
|
|
|
The JDK now exchanges DTLS cookies for all handshakes, new and
|
|
|
|
|
resumed. The previous behaviour can be re-enabled by setting the new
|
|
|
|
|
system property `jdk.tls.enableDtlsResumeCookie` to `false`.

Pattern Matching for switch

|
|
|
|
2021-09-27 01:42:03 +00:00
|
|
|
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.

deconstruct record values. Record patterns and type patterns can be

nested to enable a powerful, declarative, and composable form of data

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)
|
2022-07-11 14:10:14 +00:00

introduced in OpenJDK 16 (JEP 338). A second round of incubation took
|
2022-08-29 00:31:15 +00:00
|
|
|
place in OpenJDK 17 (JEP 414), OpenJDK 18 (JEP 417) saw a third and

|
|
|
OpenJDK 19 sees its fourth (JEP 426).

Foreign Function & Memory API

|
|
|
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.
|
|
|
|
|
|
2022-08-29 00:31:15 +00:00
|
|
|
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).

Virtual Threads

|

2022-08-29 00:31:15 +00:00
|
|
|
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.

Structured Concurrency

|

2022-08-29 00:31:15 +00:00
|
|
|
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.

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.
