JDK 23

Description
Using the reflected field of java.lang.Class componentType on a non-class argument will get IllegalArgumentException because of the way Hotspot uses it internally.  This private field is an internal implementation detail and only valid for array classes.
Comments
This doesn't warrant a release note for this severity of problem.
