Comments
I believe this issue has been fixed a while back through https://bugs.openjdk.java.net/browse/JDK-8275509. In fact, the test being noted in this JBS title was problem listed before that fix and we removed it from the problem list after the fix through https://bugs.openjdk.java.net/browse/JDK-8276688. I haven't seen this fail after that change. So I think this issue can be closed.

I would have to suspect this is the same underlying issue as JDK-8217166, even if the test itself is new.
