This test fails intermittently with exit value 137 in CI pipelines. This error code corresponds to OOM killer.

The test runs with "-Xms9G -Xmx9G" on smaller memory instances (15 GB memory total), concurrently with many other tests.

We think it would be good to add "@requires os.maxMemory > 15g" to effectively disable this test on instances as small as our typical regression testing host.

Failures seen so far typically happen with traditional (non-generational) Shenandoah.
