Hi @GoeLin . We ran the test through tier1-2 and JCK on many platforms. For production services, we have only tested on the service that has been seeing this issue.

We plan to release this patch in our January JDK release. We will do significantly more testing a week before the release. If it feels safer, I can wait to merge this patch after our users use the new JDK release for 2 weeks and we don't see issues.
