  if by memory management you mean VM memory management, please keep us
posted.

You may also be able to filter out known issues by looking through the
bug tracker: a query like this in the "advanced" search yields quite a
few issues "project = JDK AND issuetype in (Bug, Enhancement, JEP) AND
status in (Open, "In Progress", New) AND component = hotspot AND
Subcomponent = gc".

Many of those are probably overly specific though.

Thanks,
