It would originally intermittently fail if the JVM exited before it had time to publish the events so now it loops and forces GCs to encourage event publishing. The test fails if the events are received in the incorrect order (such as an unload before a load) or if the correct events are not received and the test times out.

@chadrako  Thanks for all improvements!
Friendly reminder - you need to wait for some reasonable until review from all people that has concerns. Just to ensure that you all are in agreement.
Also, https://openjdk.org/guide/#hotspot-development says specific Hotspot rules. At least to reviews are needed for any non-trivial change.
