59f4c0
JDK-8277157: Vector should throw ClassNotFoundException for a missing class of an element
59f4c0
=========================================================================================
59f4c0
`java.util.Vector` is updated to correctly report
59f4c0
`ClassNotFoundException that occurs during deserialization using
59f4c0
`java.io.ObjectInputStream.GetField.get(name, object)` when the class
59f4c0
of an element of the Vector is not found. Without this fix, a
59f4c0
`StreamCorruptedException` is thrown that does not provide information
59f4c0
about the missing class.

The following root certificate from Google has been removed from the
59f4c0
`cacerts` keystore:
59f4c0

59f4c0
============================================================================
59f4c0
The initialization of the `file.encoding` system property on non macOS
59f4c0
platforms has been reverted to align with the behavior on or before
59f4c0
JDK 11.  This has been an issue especially on Windows where the system
59f4c0
and user's locales are not the same.

JDK-8277533: ZGC: Fixed long Process Non-Strong References times
59f4c0
================================================================
59f4c0
A bug has been fixed that could cause long "Concurrent Process
59f4c0
Non-Strong References" times with ZGC. The bug blocked the GC from
59f4c0
making significant progress, and caused both latency and throughput
59f4c0
issues for the Java application.
f8e459
59f4c0
The long times could be seen in the GC logs when running with `-Xlog:gc*` e.g.

IANA Time Zone Database, on which JDK's Date/Time libraries are based,
59f4c0
has been updated to version 2021c
59f4c0
(https://mm.icann.org/pipermail/tz-announce/2021-October/000067.html). Note
59f4c0
that with this update, some of the time zone rules prior to the year
59f4c0

59f4c0
with 2021b. For more detail, refer to the announcement of 2021b

59f4c0
59f4c0
Extend the `switch` statement so that it can be used as either a
59f4c0
statement or an expression, and that both forms can use either a
59f4c0
"traditional" or "simplified" scoping and control flow behavior.  Both
59f4c0
forms can use either traditional `case ... :` labels (with fall
59f4c0
through) or new `case ... ->` labels (with no fall through), with a
59f4c0
further new statement for yielding a value from a `switch`
59f4c0
expression. These changes will simplify everyday coding, and also
59f4c0
prepare the way for the use of pattern matching in `switch`.
59f4c0
59f4c0
This was a preview feature (http://openjdk.java.net/jeps/12) in

59f4c0
59f4c0
Enhance the Java programming language with pattern matching for the
59f4c0
`instanceof` operator. Pattern matching allows common logic in a
59f4c0
program, namely the conditional extraction of components from objects,
59f4c0
to be expressed more concisely and safely.

Restore Always-Strict Floating-Point Semantics
59f4c0
==============================================
59f4c0
https://openjdk.java.net/jeps/306
59f4c0
59f4c0
Make floating-point operations consistently strict, rather than have
59f4c0
both strict floating-point semantics (`strictfp`) and subtly different
59f4c0
default floating-point semantics. This will restore the original
59f4c0
floating-point semantics to the language and VM, matching the
59f4c0
semantics before the introduction of strict and default floating-point
59f4c0
modes in Java SE 1.2.

Pattern Matching for switch
59f4c0
===========================
59f4c0
https://openjdk.java.net/jeps/406
59f4c0
59f4c0
Enhance the Java programming language with pattern matching for
59f4c0
`switch` expressions and statements, along with extensions to the
59f4c0
language of patterns. Extending pattern matching to `switch` allows an
59f4c0
expression to be tested against a number of patterns, each with a
59f4c0
specific action, so that complex data-oriented queries can be
59f4c0

JVM Constants API
59f4c0
=================
59f4c0
https://openjdk.java.net/jeps/334
59f4c0
59f4c0
Introduce an API to model nominal descriptions of key class-file and
59f4c0
run-time artifacts, in particular constants that are loadable from the
59f4c0
constant pool.
59f4c0
59f4c0

59f4c0
=================================
59f4c0
https://openjdk.java.net/jeps/353
59f4c0
59f4c0
Replace the underlying implementation used by the `java.net.Socket`
59f4c0
and `java.net.ServerSocket` APIs with a simpler and more modern
59f4c0
implementation that is easy to maintain and debug. The new
59f4c0
implementation will be easy to adapt to work with user-mode threads,
59f4c0
a.k.a. fibers, currently being explored in Project Loom

================================
59f4c0
https://openjdk.java.net/jeps/352
59f4c0
59f4c0
Add new JDK-specific file mapping modes so that the `FileChannel` API
59f4c0
can be used to create `MappedByteBuffer` instances that refer to
59f4c0
non-volatile memory.
59f4c0

https://openjdk.java.net/jeps/383
59f4c0
https://openjdk.java.net/jeps/393
59f4c0
59f4c0
Introduce an API to allow Java programs to safely and efficiently
59f4c0
access foreign memory outside of the Java heap.
59f4c0
59f4c0
This was a incubation feature (https://openjdk.java.net/jeps/11) in
59f4c0
OpenJDK 14, 15 & 16, now superseded by the Foreign Function & Memory
59f4c0
API in OpenJDK 17 (see below).

Edwards-Curve Digital Signature Algorithm (EdDSA)
59f4c0
=================================================
59f4c0
https://openjdk.java.net/jeps/339
59f4c0
59f4c0
Implement cryptographic signatures using the Edwards-Curve Digital
59f4c0

Hidden Classes
59f4c0
==============
59f4c0
https://openjdk.java.net/jeps/371
59f4c0
59f4c0
Introduce hidden classes, which are classes that cannot be used
59f4c0
directly by the bytecode of other classes. Hidden classes are intended
59f4c0
for use by frameworks that generate classes at run time and use them
59f4c0
indirectly, via reflection. A hidden class may be defined as a member
59f4c0
of an access control nest (https://openjdk.java.net/jeps/181), and may
59f4c0
be unloaded independently of other classes.
59f4c0
59f4c0
Reimplement the Legacy DatagramSocket API
59f4c0
=========================================
59f4c0
https://openjdk.java.net/jeps/373
59f4c0
59f4c0
Replace the underlying implementations of the
59f4c0
`java.net.DatagramSocket` and `java.net.MulticastSocket` APIs with
59f4c0
simpler and more modern implementations that are easy to maintain and
59f4c0
debug. The new implementations will be easy to adapt to work with
59f4c0
virtual threads, currently being explored in Project Loom
59f4c0
(https://openjdk.java.net/projects/loom). This is a follow-on to JEP
59f4c0
353 (see above), which already reimplemented the legacy Socket API.

https://openjdk.java.net/jeps/338
59f4c0
https://openjdk.java.net/jeps/414
59f4c0
59f4c0
Provide an initial iteration of an incubator module,
59f4c0
`jdk.incubator.vector`, to express vector computations that reliably
59f4c0
compile at runtime to optimal vector hardware instructions on
59f4c0
supported CPU architectures and thus achieve superior performance to
59f4c0
equivalent scalar computations.
59f4c0
59f4c0
This is an incubation feature (https://openjdk.java.net/jeps/11)
59f4c0

Unix-Domain Socket Channels
59f4c0
===========================
59f4c0
https://openjdk.java.net/jeps/380
59f4c0
59f4c0
Add Unix-domain (`AF_UNIX`) socket support to the socket channel and
59f4c0
server-socket channel APIs in the `java.nio.channels` package. Extend
59f4c0
the inherited channel mechanism to support Unix-domain socket channels
59f4c0
and server socket channels.

59f4c0
==============================
59f4c0
https://openjdk.java.net/jeps/389
f8e459
59f4c0
Introduce an API that offers statically-typed, pure-Java access to
59f4c0
native code. This API, together with the Foreign-Memory API (see
59f4c0
above), will considerably simplify the otherwise error-prone process
59f4c0
of binding to a native library.
f8e459
59f4c0
This was an incubation feature (https://openjdk.java.net/jeps/11)

https://openjdk.java.net/jeps/396
59f4c0
https://openjdk.java.net/jeps/403
59f4c0
59f4c0
Strongly encapsulate all internal elements of the JDK by default,
59f4c0
except for critical internal APIs such as `sun.misc.Unsafe`.  It will
59f4c0
no longer be possible to relax the strong encapsulation of internal
59f4c0
elements via a single command-line option, as was possible in OpenJDK
59f4c0
9 through 16.
59f4c0
59f4c0
Enhanced Pseudo-Random Number Generators
59f4c0
========================================
59f4c0
https://openjdk.java.net/jeps/356
59f4c0
59f4c0
Provide new interface types and implementations for pseudo-random
59f4c0
number generators (PRNGs), including jumpable PRNGs and an additional
59f4c0
class of splittable PRNG algorithms (LXM).
59f4c0
59f4c0
Foreign Function & Memory API
59f4c0
=============================
59f4c0
https://openjdk.java.net/jeps/412
59f4c0
59f4c0
Introduce an API by which Java programs can interoperate with code and
59f4c0
data outside of the Java runtime. By efficiently invoking foreign
59f4c0
functions (i.e., code outside the JVM), and by safely accessing
59f4c0
foreign memory (i.e., memory not managed by the JVM), the API enables
59f4c0
Java programs to call native libraries and process native data without
59f4c0
the brittleness and danger of JNI.
59f4c0
59f4c0
This API is an incubation feature (https://openjdk.java.net/jeps/11)
59f4c0
introduced in OpenJDK 17, and is an evolution of the Foreign Memory
59f4c0
Access API (OpenJDK 14 through 16) and Foreign Linker API (OpenJDK
59f4c0
16) (see above).
59f4c0

Context-Specific Deserialization Filters
59f4c0
========================================
59f4c0
https://openjdk.java.net/jeps/415
59f4c0
59f4c0
Allow applications to configure context-specific and
59f4c0
dynamically-selected deserialization filters via a JVM-wide filter
59f4c0
factory that is invoked to select a filter for each individual
59f4c0
deserialization operation.

https://openjdk.java.net/jeps/189
59f4c0
https://openjdk.java.net/jeps/379
59f4c0
59f4c0
Add a new garbage collection (GC) algorithm named Shenandoah which
59f4c0
reduces GC pause times by doing evacuation work concurrently with the
59f4c0
running Java threads.  Pause times with Shenandoah are independent of
59f4c0
heap size, meaning you will have the same consistent pause times
59f4c0
whether your heap is 200 MB or 200 GB.
59f4c0
59f4c0
Shenandoah has been provided in Red Hat builds of OpenJDK 8 since
59f4c0
8u131 in April 2017 and in all 11u builds.
59f4c0
59f4c0
Upstream, it was introduced in OpenJDK 12 as an experimental feature
59f4c0
and became a production feature in OpenJDK 15. It was backported to
59f4c0
OpenJDK 11 with the 11.0.9 release in October 2020.

59f4c0
59f4c0
Extend application class-data sharing to allow the dynamic archiving
59f4c0
of classes at the end of Java application execution. The archived
59f4c0
classes will include all loaded application classes and library
59f4c0
classes that are not present in the default, base-layer CDS archive.

59f4c0
59f4c0
Designate the primitive wrapper classes as value-based and deprecate
59f4c0

59f4c0
====================================
59f4c0
https://openjdk.java.net/jeps/398
59f4c0
59f4c0
Deprecate the Applet API for removal.  It is essentially irrelevant
59f4c0
since all web-browser vendors have either removed support for Java
59f4c0
browser plug-ins or announced plans to do so.
59f4c0

59f4c0
==========================================
59f4c0
https://openjdk.java.net/jeps/411
59f4c0
59f4c0
Deprecate the Security Manager for removal in a future release. The
59f4c0
Security Manager dates from Java 1.0. It has not been the primary
59f4c0
means of securing client-side Java code for many years, and it has
59f4c0
rarely been used to secure server-side code. To move Java forward, we
59f4c0

Remove the Experimental AOT and JIT Compiler

============================================

59f4c0
Remove the experimental Java-based ahead-of-time (AOT) and
59f4c0
just-in-time (JIT) compiler.  This compiler has seen little use since
59f4c0
its introduction and the effort required to maintain it is
59f4c0
significant.  Retain the experimental Java-level JVM compiler
59f4c0
interface (JVMCI) so that developers can continue to use
59f4c0
externally-built versions of the compiler for JIT compilation.
