A DESCRIPTION OF THE PROBLEM :
When calling "ProcessHandle.current().info().command().orElse(null)" from a VM with -Xcheck:jni enabled, Java emits the following warnings:

WARNING: JNI local refs: 33, exceeds capacity: 32
at java.lang.ProcessHandleImpl$Info.info0(java.base@19.0.2/Native Method)
at java.lang.ProcessHandleImpl$Info.info(java.base@19.0.2/ProcessHandleImpl.java:607)
at java.lang.ProcessHandleImpl.info(java.base@19.0.2/ProcessHandleImpl.java:524)
at ...

This warning makes it difficult to use -Xcheck:jni as a validation step to find bugs in our own code.
 
The bug does not occur with IBM Semeru, for example.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Launch java with code that calls "ProcessHandle.current().info().command().orElse(null)", and has "-Xcheck:jni" enabled.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No warnings from Java SDK code

ACTUAL -
Several occurrences of
