Notes on individual issues:
===========================
security-libs/java.security:
JDK-8281658: Add a security category to the java -XshowSettings option
======================================================================
The `-XshowSettings` launcher option now has a 'security' category, allowing
the following arguments to be passed:
* -XshowSettings:security or -XshowSettings:security:all: show all security settings and continue
* -XshowSettings:security:properties - show security properties and continue
* -XshowSettings:security:providers - show static security provider settings and continue
* -XshowSettings:security:tls - show TLS related security settings and continue
The output will include third-party security providers if they are
included in the application class path or module path, and configured
in the java.security file.
JDK-8316138: Add GlobalSign 2 TLS root certificates
===================================================
The following root certificates have been added to the cacerts
truststore:
Name: GlobalSign
Alias Name: globalsignr46
Distinguished Name: CN=GlobalSign Root R46, O=GlobalSign nv-sa, C=BE
Name: GlobalSign
Alias Name: globalsigne46
Distinguished Name: CN=GlobalSign Root E46, O=GlobalSign nv-sa, C=BE
JDK-8328638: Fallback Option For POST-only OCSP Requests
========================================================
JDK-8179503, introduced in OpenJDK 17, added support for using the
HTTP GET method for OCSP requests. This was turned on unconditionally
for small requests.
RFC 5019 and RFC 6960 explicitly allow and recommend the use of HTTP
GET requests. However, some OCSP responders have been observed to not
work well with such requests.
With this release, the JDK system property
`com.sun.security.ocsp.useget` is introduced. The default setting is
'true' which retains the current behaviour of using GET requests for
small requests. If the property is instead set to 'false', only HTTP
POST requests will be used, regardless of size.
This option is non-standard and may be removed again if problematic
OCSP responders are no longer an issue.
infrastructure/build:
JDK-8326891: Prefer RPATH over RUNPATH for $ORIGIN rpaths in internal JDK binaries
==================================================================================
Native executables and libraries in the JDK use embedded runtime
search paths to locate required internal JDK native libraries. On
Linux systems, there are two ways of specifying these search paths;
DT_RPATH and DT_RUNPATH.
The main difference between the two options is that paths specified by
DT_RPATH are searched before those in the LD_LIBRARY_PATH environment
variable, whereas DT_RUNPATH paths are considered afterwards. This
means the use of DT_RUNPATH can allow JDK internal libraries to be
overridden by libraries of the same name found on the LD_LIBRARY_PATH.
Builds of earlier OpenJDK releases left the choice of which type of
runtime search path to use down to the default of the linker. With
this release, the option `--disable-new-dtags` is explicitly passed to
the linker to avoid setting DT_RUNPATH.
JDK-8295111: dpkg appears to have problems resolving symbolically linked native libraries
=========================================================================================
The jpackage tool uses `dpkg -S` to lookup which package provides a
particular file on Debian and Ubuntu systems. However, on newer Debian
and Ubuntu systems, `dpkg -S` does not resolve symlinks. In this
OpenJDK release, jpackage now resolves symlinks before passing the
real path of the file to dpkg.
hotspot/gc:
JDK-8314573: G1: Heap resizing at Remark does not take existing eden regions into account
=========================================================================================
To comply with the settings of `-XX:MinHeapFreeRatio` and
`-XX:MaxHeapFreeRatio`, the G1 garbage collector adjusts the Java heap
size during the Remark phase, keeping the number of free regions
within these bounds.
In earlier OpenJDK releases, Eden regions were considered to be
occupied or full for this calculation. This made the heap size
dependent on the Eden occupancy at the time the Remark phase was
run. However, after the next garbage collection, these Eden regions
would be empty.
With this OpenJDK release, Eden regions are now considered empty or
free during the Remark phase calculation. The overall effect is that
G1 now expands the Java heap less aggressively and more
determinstically, as the number of free regions does not vary as much.
It also aligns Java heap sizing with the full GC heap sizing.
However, this may potentially lead to more garbage collections.
JDK-8315503: G1: Code root scan causes long GC pauses due to imbalanced iteration
=================================================================================
The Code Root Scan phase of garbage collection finds references to
Java objects within compiled code. To speed up this process, a cache
is maintained within each region of the compiled code that contains
references into the Java heap.
On the assumption that the set of references was small, previous
releases used a single thread per region to iterate through these
references. This introduced a scalability bottleneck, where
performance could be reduced if a particular region contained a large
number of references.
In this release, multiple threads are used, removing this bottleneck.
JDK-8326092: Pause Remark sometimes has extremely long pause times on class unloading
=====================================================================================
In earlier releases of OpenJDK 21, applications could experience long
pause times during Stop The World (STW) garbage collection. This issue
affected various phases of the collection pauses, including Class
Unloading, Root Scanning, and CodeCache Unloading, in all STW garbage
collectors; the Serial, Parallel, and G1 collectors.
In this release, these performance problems are resolved through
backports of garbage collection work on OpenJDK 22.
