Greetings,
During the investigation around a potential memory leak, initially thought to be related to JFR and OldObjectSamples, but eventually reduced to https://bugs.openjdk.org/browse/JDK-8303767, a few minor improvements were made.
There is no need to save class unload typesets if there are no new unresolved entries for the epoch in the priority queue.
Testing: jdk_jfr, stress testing
Thanks
Markus
