8316241: Test jdk/jdk/jfr/jvm/ failed #17328

@mgronlun mgronlun commented Jan 9, 2024


This fix allows JFR artefact tagging to become deep instead of insufficiently shallow. It adjusts a race condition where one thread tags a class as being in use while another thread tags a class to be both method and used.

Testing: jdk_jfr, stress_testing
