One other suggestion is to use a try-finally block here. Put L48-53 in the
block and set shouldFinish in the finally block. That way if the test fails
then it won't leave a spinning thread to disrupt the next test that runs in the
agent VM.
Also just to say that we've mostly used JUnit for new tests in recent releases,
moving away from TestNG for new tests.
