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.

The test installs a security manager and that has to be present during the call to getDefault() when getDefault() does the real work (not just reading from the cache). Setting -Duser.timezone will not help as the only fix.
