     Your comment in the bug says this:

     > One test is testing 1k, 16k, etc, which seems extreme.

     but you also took out this test case:

     > -XX:SurvivorAlignmentInBytes=512

     so your largest test case is now:

     > -XX:SurvivorAlignmentInBytes=256

     You might want to update the bug report to match this fix.

Thumbs up (modulo hs-tier[1-3] testing.
