Re: JDK 23 Feature Freeze / New Loom EA builds
by Yoann Rodiere
Hey David,
Since it's been a while, I'll confirm all is well on Hibernate projects:
Hibernate ORM: Version 6.6 tested against JDK 23 (EA 26) / 24 (EA 1). No
problems to report.
Hibernate Validator: Version 8.0 tested against JDK 23 (EA 26) / 24 (EA 1).
No problems to report.
Hibernate Search: Version 7.2 tested against JDK 23 (EA 26) / 24 (EA 1). No
problems to report.
Hibernate Reactive: Version 2.3 tested against JDK 23 (EA 26) / 24 (EA 1).
No problems to report.
Have a nice day,
Yoann Rodière

Hibernate Search 7.2.0.Alpha2 released
by Marko Bekhta
Hello,
We just published Hibernate Search 7.2.0.Alpha2, the second alpha release
of the next minor version of Hibernate Search.
We are pleased to announce that Hibernate Search 7.2.0.Alpha2 is licensed
under Apache License 2.0, which will be the license for all releases of
Hibernate Search in the 7.2 series and later. This change is a part of a
broader initiative to re-license Hibernate projects with the Apache License
2.0 [1].
Compared to the previous alpha, besides the license change this version
contains predicate improvements, upgrades Lucene and Hibernate ORM
dependencies, includes compatibility with the latest Elasticsearch 8.14 and
more.
See our blog for more information [2].

JDK 23 Feature Freeze / New Loom EA builds
by David Delabassee
Welcome to the latest OpenJDK Quality Outreach update!
JDK 23, scheduled for General Availability on September 17, 2024, is now in Rampdown Phase One (RDP1) [1]. At this point, the overall JDK 23 feature set is frozen (see the final list of JEPs integrated into JDK 23 below) and only low-risk enhancements might still be considered. The coming weeks should be leveraged to identify and resolve as many issues as possible, i.e. before JDK 23 enters the Release Candidates phase in early August [2]. We count on you to test your projects and help us make JDK 23 another solid release!
This time, we are covering several heads-up related to JDK 23 : Deprecate the Memory-Access Methods in sun.misc.Unsafe for Removal and default annotation processing policy change. Also, make sure to check the new Loom early-access builds which have an improved Java monitors implementation to work better with virtual threads.
[1] https://mail.openjdk.org/pipermail/jdk-dev/2024-June/009053.html
[2] https://openjdk.org/projects/jdk/23/
## Heads-Up - JDK 23: Deprecate the Memory-Access Methods in sun.misc.Unsafe for Removal
As mentioned in a previous communication [3], there’s a plan to ultimately remove the sun.misc.Unsafe memory-access methods as the platform offers safer alternatives. JEP 471 (Deprecate the Memory-Access Methods in sun.misc.Unsafe for Removal) [4] outlines in more detail this plan including the initial step which is happening in JDK 23, i.e., all of the sun.misc unsafe memory-access methods are now marked as deprecated for removal. This will cause, in JDK 23, compile-time deprecation warnings for code that refers to these methods, alerting library developers to their forthcoming removal. A new command-line option also enables application developers and users to receive runtime warnings when those methods are used.
Developers relying on those sun.misc.Unsafe APIs for access memory are strongly encouraged to start, if they haven't done so yet, the migration from the sun.misc.Unsafe APIs to supported replacements. For more details, make sure to read JEP 471 (Deprecate the Memory-Access Methods in sun.misc.Unsafe for Removal).
[3] https://mail.openjdk.org/pipermail/quality-discuss/2024-January/001132.html
[4] https://openjdk.org/jeps/471
## Heads-Up - JDK 23: Changes Default Annotation Processing Policy
Annotation processing is a compile-time feature, where javac scans the to-be-compiled source files for annotations and then the class path for matching annotation processors, so they can generate source code. Up to JDK 22, this feature is enabled by default, which may have been reasonable when it was introduced in JDK 6 circa 2006, but from a current perspective, in the interest of making build output more robust against annotation processors being placed on the class path unintentionally, this is much less reasonable. Hence, starting with JDK 23, javac requires an additional command-line option to enable annotation processing.
### New `-proc` Value
To that end, the pre-existing option `-proc:$policy` was extended, where `$policy` can now have the following values:
- `none`: compilation _without_ annotation processing, this policy exists since JDK 6
- `only`: annotation processing _without_ compilation, this policy exists since JDK 6
- `full`: annotation processing followed by compilation, this policy is the default in JDK ≤22 but the value itself is new (see next section for versions that support it)
Up to and including JDK 22, code bases that require annotation processing before compilation could rely on javac's default behavior to process annotations but that is no longer the case. Starting with JDK 23, at least one annotation-processing command line option needs to be present. If neither `-processor`, `--processor-path`, now `--processor-module-path` is used, `-proc:only` or `-proc:full` has to be provided. In other words, absent other command line options, `-proc:none` is the default on JDK 23.
### Migration to `-proc:full`
Several measures were undertaken to help projects prepare for the switch to `-proc:full`:
- As of the April 2024 JDK security updates, support for `-proc:full` has been backported to 17u (17.0.11) and 11u (11.0.23) for both Oracle JDK and OpenJDK distributions. Additionally, Oracle's 8u release (8u411) also supports `-proc:full`.
- Starting in JDK 21, javac prints an informative message if implicit usage of annotation processing under the default policy is detected.
With `-proc:full` backported, it is possible to configure a build that will work the same before and after the change in javac's default policy.
Additional details can be found in the original proposal [5].

## Heads-up - Loom: New EA builds with improved Java monitors implementation to work better with virtual threads
Project Loom published new early-access builds [6]. These builds have an improved object monitor implementation that should prevent virtual threads from pinning their carrier thread in the following situations:
- when blocking on entering a synchronized method/statement because the object's associated monitor is held by another thread,
- when parking (e.g. when doing socket I/O) while in a synchronized method,
- when calling `Object.wait` while in a synchronized method.
The changes for `Object.wait`/timed-`wait` is the main change since the previous Loom EA build.
The Loom team is looking for help to test the changes, i.e., trying out these builds with code that is known to use virtual threads and with libraries that are "very synchronized". The primary goal is to gauge both reliability and performance. Right now, the focus is on being functional and reliable. Please note that the performance for some cases isn't yet fully on par with blocking on j.u.concurrent locks and condition objects.
As before, JFR events can be used to identify remaining cases of pinning, parking or blocking in a class initializer for example. The system property `jdk.tracePinnedThreads`, which used to print stack traces when threads are pinned, no longer outputs anything.
Please send feedback via email to the Loom mailing list [7] (subscription required).
