Also there is an issue with TestProcessLauncher.quit() method. General schema of the testcases is TestProcessLauncher t = ...; try { t.launch(); .. perform testing ... } finally { t.quit(); } But if target VM failed to connect to IOPipe t.quit() throws new exception as it tests only that IOPipe object is not null, but does not verify it's connected

The logic of the test is: - creates target VM; - creates server part of IOPipe to communicate with target VM; - target VM connects to IOPipe socket. The reason of the failure is target VM is started too fast and tries to connect to IOPipe before the test starts listening. Looks like this is common logic for many tests in nsk (which use IOPipe to communicate with debuggee), so we can get similar failures with other tests.

Resetting to New to we can triage this CR again and figure out how to handle it.
