We tried to fix this issue by removing one source of allocations (see JDK-8308043), but that there are still more reasons why the JVM might allocate memory in the test. The test has a history of causing timeouts (likely caused by deadlocks), but we're currently only seeing hangs with Generational ZGC. I propose that we turn off this test for Generational ZGC, and if the test still cause problems in other configurations then we'll reevaluate if this should be handled some other way.

Looks good.
