The jvm option `-Xcomp` will make `BackgroundCompilation` false. In this test, disable `BackgroundCompilation` will make `instrumentation` in `premain` throw `java.util.MissingResourceException` in some test  environments.

Yes, I think more information needed as the JBS issue suggests the ClassCircularityError happens before main. If there was something fundamental here then I would expect every JDK tests for Java Agents to fail with -Xcomp. In addition to the locale, can you confirm that you are testing an images build and not an exploded build?
