Question on status of a few bugs in OpenJDK 6

OpenJDK6 is driven mostly by the contributors. It is not an extremely active development forest.
The jdk6-dev AT openjdk.java.net alias is the communication path, and yes it's very quiet of late.
I usually do the approvals of changes and will co-ordinate any new releases, but I let the community
drive what gets into it for the most part. Hopefully I'm approving the correct changes, and rejecting
the right ones. I would of course require that any OpenJDK6 hotspot changes will have been reviewed
by the appropriate hotspot team members.
Significant changes might not be a good idea, with OpenJDK6 it's mostly 'let sleeping dogs lie' ;^)
