>> The problem with the test is that it fails when running with Java Flight Recorder enabled. This is because JFR will call TimeZone.getDefault() when it starts up, before the main() method is called. This will cause TimeZone to cache the value so that when the test calls TimeZone.getDefault() it will get the old value. The solution here is to reset the value in the beginning of the test.

Good point. I can fix that, too.
