After JDK-8363949 fixed the test header and enabled test execution, the test runtime/Monitor/MonitorWithDeadObjectTest.java#DumpThreadsBeforeDetach fails on Linux Alpine in fastdebug .
Error output is
Error: Calling getThreadMXBean()
result: Failed. Unexpected exit from test [exit code: 255]

After enhancing check_exception, we see this :
