Byteman 4.0.5 is now available from the Byteman downloads page and from the Maven Central repository. It is the latest update release for use on JDK9+ runtimes. It is also recommended as the preferred release for use on JDK8- runtimes.
4.0.5 updates the 4.0.4 release to ensure that it works correctly on
the latest jdk12 releases. Specifically, it ensures that Byteman is able
to process class files with a JDK12 class file version (the previous
release would run on jdk12 but could only classes whose bytecode file
version was for jdk11 or lower.
4.0.5 also fixes a small bug which broke access to non-public members of classes when loaded via a JBoss Modules class loader.
More details can be found in the Release Notes.
