result: Failed. Unexpected exit from test [exit code: 96]

There's no core file or hs_err_pid file in the artifacts. I have
no idea where the "exit code 96" came from.

There's another unresolved bug for this test:

JDK-8228404 vmTestbase/nsk/jvmti/scenarios/hotswap/HS204/hs204t001/hs204t001.java crashed with AssertionError
