On what issues could I help clean up for JDK 9

I'm just working with Maurizio to get OpenJDK 9/10 source code into
IntelliJ (We're waiting for the next patch release of IntelliJ to come out
of EA). That will make reading the source code and running jtreg tests
That will personally help me start looking through a number of bugs and
starting discussions on whether or not they're suitable as beginning bugs.
@Dalibor - that classification link is very useful, thanks!
