A DESCRIPTION OF THE PROBLEM :
Given a test case, we found that the execution results of this test case on different JVMs and different versions are quite different, the simplified test case can be found in the attachment. In summary, J9(1.8.0_292) and hotspot(8u275b01) are executed normally, while others threw different exceptions. We first speculated that it was a J9 problem, but the developers of J9 gave us a reasonable explanation, for more information: https://github.com/eclipse-openj9/openj9/issues/13082. Hope it helps.

REGRESSION : Last worked in version 8

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Follow the commands in readme.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Run normally
ACTUAL -
NoSuchMethodException
