java/lang/ScopedValue/StressStackOverflow.java may be a bit unstable with some VM options, and also with JTREG_TEST_THREAD_FACTORY=Virtual runs. The test was excluded via an entry in ProblemList-Virtual.txt in the loom repo and we didn't bring over that exclude to the main line as part of JEP 446.

Here's one sighting on linux-aarch64 with JTREG_TEST_THREAD_FACTORY=Virtual and -XX:-TieredCompilation. Another failure mode is timeout.
