<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">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!<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">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.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">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).<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">## Heads-Up - JDK 23: Changes Default Annotation Processing Policy<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">### New `-proc` Value<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">To that end, the pre-existing option `-proc:$policy` was extended, where `$policy` can now have the following values:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">- `none`: compilation _without_ annotation processing, this policy exists since JDK 6<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">- `only`: annotation processing _without_ compilation, this policy exists since JDK 6<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">- `full`: annotation processing followed by compilation, this policy is the default in JDK ¡Â22 but the value itself is new (see next section for versions that support it)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">### Migration to `-proc:full`<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">Several measures were undertaken to help projects prepare for the switch to `-proc:full`:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">- 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`.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">- Starting in JDK 21, javac prints an informative message if implicit usage of annotation processing under the default policy is detected.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">Additional details can be found in the original proposal [5].<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">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:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">- when blocking on entering a synchronized method/statement because the object's associated monitor is held by another thread,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">- when parking (e.g. when doing socket I/O) while in a synchronized method,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">- when calling `Object.wait` while in a synchronized method.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">The changes for `Object.wait`/timed-`wait` is the main change since the previous Loom EA build.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;mso-ligatures:none">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.<o:p></o:p></span></p>
