Move forward for JDK-8029891

[Tristan Yan]

Hi Mandy

We have discussed bug https://bugs.openjdk.java.net/browse/JDK-8029891 in JBS. And we don't think this is a good time to fix it. I suggest we do two things for this bug if it's okay for you.
1. We open a new JDK bug for tracking down future JDK change. Also link JDK-8029891 to this new jdk bug.
2. We put java/lang/ClassLoader/deadlock/GetResource.java to ProblemList.
Please let know if you agree this.
Thank you.
Tristan
