I don’t think it’s a duplicate.

8196611 is a test bug.  The test isn’t prepared for significant additional allocation
by code other than the test, e.g. by some background task like Graal compilation.

218176 seems to be a Graal problem.  The test is fine, it intentionally triggers OOMEs
and handles them appropriately.  However, a background task, like Graal compilation,
might also encounter OOME because of what the test is doing.  Graal compilation
seems to be insufficiently resilient to OOME and the process terminates as a result.
