It's observed that some of the JCK tests related to Annotation processing are failing in JDK 22-b23 with "java.lang.AssertionError: Cannot add metadata to this type: VOID"
Possibly a regression caused by - https://bugs.openjdk.org/browse/JDK-8225377

The tests are passing with JDK22-b22.

Attaching the sample AnnotationProcessor with sample target class file (Tester)

Here is the observation :
====

With b-22 ( Tester class successfully parsed by Annotation Processor)
====
/scratch/jdk-cache/22/22/jdk-22/bin/javac -processor AnnoProc Tester
init...
process...
  annotations []

With b-23 ( java.lang.AssertionError: Cannot add metadata to this type: VOID )
====
