You can now sign up for the Java2D bug update notifications over here:

You’ll see each bug update at the same time Sun developers see them.

Wow cool - thanks 
Would it be possible to get this as RSS feed instead?
I’ll ask the keeper.
Currently you can’t even read it unless you’re subscribed =(
Once that’s fixed you will probably be able to access it through
nabble like the other openjdk lists:
http://www.nabble.com/OpenJDK-f27642.html
and get the feed from there.
Thanks,
Dmitri
