RFR: 8222224: vmTestbase/nsk/jvmti/SingleStep/singlestep001/TestDescription.java fails

[Daniil Titov]

Please review the change that fixes intermittent failure of the test when running with Graal on.

The problem here is the similar to the one fixed in JDK-8218401, the callbacks this test enables keep processing events and perform JVMTI calls after VM is terminated. The fix ensures that the test does a quick return from the callbacks after VMDeath event is received.
