Easiest would be to modify TestCrashOnOutOfMemoryError.java - add a second `@test ` section, start the test with a different parameter that signals that you run the testee with JFR enabled, and then test for existence of the JFR dump.

It might be better to have a test in test/jdk/jdk/jfr/jvm/, where we have other crash tests.

It's probably best to create a separate test for this, as checking for OOM can be flaky, and it may need to be added to the ProblemList separately.
