Yes, we need a bug to track this work (or at least decide on a plan of action - if any). I wouldn't conflate this into this bug, though as it's not clear whether or not JFR/thread dumps should report container values. I'll try to create a bug for this consolidation effort today. ------------- PR: https://git.openjdk.java.net/jdk/pull/4702
