OpenJDK
JEP 442, Foreign Function & Memory API (Third Preview), has been promoted from Proposed to Target to Targeted status for JDK 21. This JEP incorporates refinements based on feedback and to provide a third preview from: JEP 434, Foreign Function & Memory API (Second Preview), delivered in JDK 20; JEP 424, Foreign Function & Memory API (Preview), delivered in JDK 19, and the related incubating JEP 419, Foreign Function & Memory API (Second Incubator), delivered in JDK 18; and JEP 412, Foreign Function & Memory API (Incubator), delivered in JDK 17. This feature provides an API for Java applications to interoperate with code and data outside of the Java runtime by efficiently invoking foreign functions and by safely accessing foreign memory that is not managed by the JVM. Updates from JEP 434 include: centralizing the management of the lifetimes of native segments in the Arena interface; enhanced layout paths with a new element to dereference address layouts; and removal of the VaList class.
JDK 21
Build 20 of the JDK 21 early-access builds was also made available this past week featuring updates from Build 19 that include fixes to various issues. Further details on this build may be found in the release notes.
For JDK 21, developers are encouraged to report bugs via the Java Bug Database.

The release of GlassFish 7.0.4 ships with dependency upgrades and bug fixes such as: redirections from the Admin Console that result in a blank page upon deployment/undeployment of an application; a potential leak when a resource is loaded from a class within an EAR/JAR file that is invoked from a dynamically loaded class by a custom class loader; and an empty list for configuration templates from the Admin Console upon creating new configuration. The one new feature in this new version is the ability to add methods to build classpath of the ScatteredArchive class from the current classpath. More details on this release may be found in the release notes.
