Notes on individual issues:
===========================
tools/javac:
JDK-8317300: Align `javac` with the Java Language Specification by Rejecting `final` in Record Patterns
=======================================================================================================
Java 21 enhanced the language with pattern matching for switch
statements. However, the javac compiler released with OpenJDK 21
allowed the 'final' keyword to be used in front of a record pattern
(e.g. `case final R(...) ->`), which is a violation of the Java
Language specification.
With this release of OpenJDK 21, programs using `final` within a
switch statement will now fail to compile. The erroneous keyword will
need to be removed to allow the program to be compiled.
security-libs/javax.xml.crypto:
JDK-8319124: Update XML Security for Java to 3.0.3
==================================================
The XML signature implementation in OpenJDK 21 has been updated to
Apache Santuario 3.0.3. This update introduces four new SHA-3 based
RSA-MGF1 SignatureMethod algorithms.
However, the API of javax.xml.crypto.dsig.SignatureMethod can not be
changed in update releases to provide constants for these new
algorithms. The equivalent string literals should be used as below:
* SHA3_224_RSA_MGF1: "http://www.w3.org/2007/05/xmldsig-more#sha3-224-rsa-MGF1"
* SHA3_256_RSA_MGF1: "http://www.w3.org/2007/05/xmldsig-more#sha3-256-rsa-MGF1"
* SHA3_384_RSA_MGF1: "http://www.w3.org/2007/05/xmldsig-more#sha3-384-rsa-MGF1"
* SHA3_512_RSA_MGF1: "http://www.w3.org/2007/05/xmldsig-more#sha3-512-rsa-MGF1"
hotspot/runtime:
JDK-8325496: Make TrimNativeHeapInterval a product switch
=========================================================
The option '-XX:TrimNativeHeapInterval=ms', where 'ms' is the interval
in milliseconds, is now an official product switch. It allows the
virtual machine to trim the native heap at the specified interval on
supported platforms (currently only Linux with glibc). A value of
zero (the default) disables trimming.
client-libs/java.awt:
JDK-8322750: AWT SystemTray API Is Not Supported on Most Linux Desktops
=======================================================================
The java.awt.SystemTray API is used to interact with the system's
desktop taskbar to provide notifications and may include an icon
representing an application. The GNOME desktop's support for taskbar
icons has not worked properly for several years, due to a platform
bug. This bug, in turn, affects the JDK's SystemTray support on GNOME
desktops.
Therefore, in accordance with the SystemTray API specification,
java.awt.SystemTray.isSupported() will now return false on systems
that exhibit this bug, which is assumed to be those running a version
of GNOME Shell below 45.
The impact of this change is likely to be minimal, as users of the
SystemTray API should already be able to handle isSupported()
returning false and the system tray on such platforms has already been
unsupported for a number of years for all applications.
security-libs/java.security:
JDK-8321408: Added Certainly R1 and E1 Root Certificates
========================================================
The following root certificate has been added to the cacerts
truststore:
Name: Certainly
Alias Name: certainlyrootr1
Distinguished Name: CN=Certainly Root R1, O=Certainly, C=US
Name: Certainly
Alias Name: certainlyroote1
Distinguished Name: CN=Certainly Root E1, O=Certainly, C=US
hotspot/gc:
JDK-8310031: Parallel: Precise Parallel Scanning of Large Object Arrays for Young Collection Roots
==================================================================================================
During the collection of young generation objects, the ParallelGC
collector partitions the old generation into 64kB stripes to scan for
references to the young generation. The stripes are assigned to worker
threads to do the scanning in parallel.
However, previous releases of OpenJDK 21 did not constrain these
worker threads to their own stripe. Parallelism was limited as a
single thread could end up scanning a large object with thousands of
references across multiple stripes, if it happened to start in its
allocated stripe. This also resulted in bad scaling, due to the
subsequent memory sharing associated with multiple threads working on
the same stripe.
In this release, workers are limited to their stripe and only process
interesting parts of large object arrays. Pauses for the ParallelGC
collector are now on par with the G1 collector when large object
arrays are present, reducing pause times by four to five times in some
cases.
JDK-8325074: ZGC fails assert(index == 0 || is_power_of_2(index)) failed: Incorrect load shift: 11
==================================================================================================
Running the virtual machine with `-XX:+UseZGC` and a non-default value
of `-XX:ObjectAlignmentInBytes` had the potential to crash or perform
incorrect execution. This was due to `ZBarrierSet::clone_obj_array`
not taking into account padding words at the end of an ObjArray. This
has now been rectified in this release.
Happy hacking,
