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.

The change to the test seems reasonable.

But I can't help but think that this behaviour of JFR will cause 
problems for real applications that expect to be first to access the 
timezone. Perhaps JFR should reset the timezone after it grabs a copy?
