I believe this mailing list
http://mail.openjdk.java.net/mailman/listinfo/core-libs-dev
is the appropriate team to bring this to. This project list is focused
on packaging
It'll help if you can reference a bug (or file a new one if necessary).
I did a little bit of looking and didn't find anything, but this appears
to be interesting too. There must be an existing bug report on this, as
use of system timezone data is clearly desirable.
