Hi dean,

  Currently there is not a master bug for this issue. A similar issue is JDK-8216181, but it is not entirely same. I'm not sure whether the root cause is the same one. So I will make this issue as the master bug and create another SubTask for it. Thanks.

Isn't it the correct process that there should be a master bug for fixing the test or underlying issue, then use that bug number for the problem list entry, and push it using a SubTask.  For example, see the relationship between JDK-8229447 and JDK-8229446 as an example.
