JDK-8307958 changed the metaspace verification to no run as often by default . This change was to combat the extrem slowdown that could occur when many class loaders were constantly loaded and dropped in combination with infrequent class unloading triggered by the gc.

To make it easier to identify if future changes will introduce similar slowdowns, a fuzzy class unloading test should be created which can be tuned to test for these kind of regressions.

This test should also be able to be run with full verification to improve upon metaspace + class unloading testing, especially since the default verification is somewhat reduced after JDK-8307958
