AFAIK, at bugs.sun.com it isn't possible to comment on bugs, watch them or vote for them anymore.
I found out there's now https://bugs.openjdk.java.net but I can't find any way to register.
So, how the hell I can follow the progress on bugs? Or add additional information if I have?
It's unbelievable that in 2013 we are still unable to have a decent bug reporting system for the JDK/JRE!!!!!
P.S.: I know this might not be the best section for this kind of question, but I couldn't find anything better in these forums...
