On what issues could I help clean up for JDK 9

My suggestion for developers who want to work on fixing some JDK cleanup
issue, and on nothing else at all, is that they should wait for a little
bit longer until JDK 10 forests are created, and then concentrate their
cleanup efforts there.
On the JDK 9 side, with the JDK 9 Rampdown Start coming up in a few
weeks, please be aware that changes for P4 and P5 issues won't be
accepted any more from then on into JDK 9 forests.
For details on the timing, please see
I would absolutely agree that it doesn't makes a lot of sense to ask
anyone to start contributing code to some "JDK 9 focused P4/P5 cleanup"
effort at this stage of JDK 9 development, in particular with the
holiday season and Feature Extension Complete dates coming up right
before Rampdown Start.
I understand that it can be a bit disappointing to be told that, but I
think that's preferable to being "mentored" into spending time on low
priority cleanups for JDK 9 that don't have a high a chance of making it
into JDK 9 on time.

I know that a new contributors should prove in a some way that they are willing to do more than one contribution. But on the other hand if I ask for help, I should also do some investment on my side.
