Simplify the implementation of the G1 garbage collector's barriers,

Ahead-of-Time Class Loading & Linking
|
||||
=====================================
|
||||
https://openjdk.org/jeps/483
|
||||
|
||||
Improve startup time by making the classes of an application instantly
|
||||
available, in a loaded and linked state, when the HotSpot Java Virtual
|
||||
Machine starts. Achieve this by monitoring the application during one
|
||||
run and storing the loaded and linked forms of all classes in a cache
|
||||
for use in subsequent runs. Lay a foundation for future improvements
|
||||
to both startup and warmup time.
|
||||
|
||||
Using this feature requires a three stage process:
|
||||
|
||||
1. Populate the Ahead-of-Time configuration data with a training run
|
||||
of the application using the options `-XX:AOTMode=record
|
||||
-XX:AOTConfiguration=<config name>` where `<config name>` is the
|
||||
configuration reference to use in #2.
|
||||
|
||||
2. Create the Ahead-of-Time cache using the options
|
||||
`-XX:AOTMode=create -XX:AOTConfiguration=<config name>
|
||||
-XX:AOTCache=<cache name>` where `<config name>` is the configuration
|
||||
reference from #1 and `<cache name>` is the cache reference to use in
|
||||
later runs.
|
||||
|
||||
3. When running the application in testing or production, use the
|
||||
option `-XX:AOTCache=<cache name>` to run the application with the
|
||||
cache generated in #2.

Synchronize Virtual Threads without Pinning

||||
===========================================
|
||||
https://openjdk.org/jeps/491
|
||||
|
||||
Improve the scalability of Java code that uses synchronized methods
|
||||
and statements by arranging for virtual threads that block in such
|
||||
constructs to release their underlying platform threads for use by
|
||||
other virtual threads. This will eliminate nearly all cases of virtual

threads being pinned to platform threads, which severely restricts the

|
||||
Issue a warning at run time on the first occasion that any
|

memory-access method in sun.misc.Unsafe is invoked. All of these
|
||||
unsupported methods were terminally deprecated in JDK 23 (see JEP 471

above). They have been superseded by standard APIs, namely the
|
||||
VarHandle API (JEP 193, OpenJDK 9) and the Foreign Function & Memory
|

API (JEP 454, OpenJDK 22). We strongly encourage library developers to

Permanently Disable the Security Manager
|
||||
========================================
|
||||
https://openjdk.org/jeps/486
|
||||
|
||||
The Security Manager has not been the primary means of securing
|
||||
client-side Java code for many years, it has rarely been used to
|
||||
secure server-side code, and it is costly to maintain. We therefore
|
||||
deprecated it for removal in OpenJDK 17 via JEP 411 (2021). As the
|
||||
next step toward removing the Security Manager, we will revise the
|
||||
Java Platform specification so that developers cannot enable it and
|
||||
other Platform classes do not refer to it. This change will have no
|
||||
impact on the vast majority of applications, libraries, and tools. We
|
||||
will remove the Security Manager API in a future release.

Deprecate the 32-bit x86 port, with the intent to remove it in a

future release. This will thereby deprecate the Linux 32-bit x86 port,
|
||||
which is the only 32-bit x86 port remaining in the JDK. It will also,
|
||||
effectively, deprecate any remaining downstream 32-bit x86
|
||||
ports. After the 32-bit x86 port is removed, the architecture-agnostic
|
||||
Zero port will be the only way to run Java programs on 32-bit x86
