RFR: ProblemList failing JMX tests that fail with the wrapper.

[Chris Plummer]

In the jdk repo, the following is being pushed:

[JDK-8291578](https://bugs.openjdk.org/browse/JDK-8291578) Remove JMX related tests from ProblemList-svc-vthreads.txt

Eventually this will make it's way into loom, which would leave these tests no longer being problem listed. As described in [JDK-8291578](https://bugs.openjdk.org/browse/JDK-8291578), these tests should be problem listed on ProblemList-vthread.txt, and this PR is taking care of that.
