ADDITIONAL SYSTEM INFORMATION :
Java 21 on Ubuntu 23.10 (mantic)

A DESCRIPTION OF THE PROBLEM :
os::current_frame() is stubbed out on armhf and thus test always fails because it can not produce native frames.
See void JavaThread::print_jni_stack() implementation.


REGRESSION : Last worked in version 21

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
test passes
ACTUAL -
test fails with
result: Failed. Execution failed: `main' threw exception: java.lang.RuntimeException: 'thread_start' missing from stdout/stderr


FREQUENCY : always
