Hi Vladimir,
Certainly. However, a fix must be pushed to the main development release
first (which is JDK 8 currently) and tested properly (for at least a few
weeks). Only then is it possible to back-port the fix to a 7 update release.
BTW, I've filed a bug for you:
http://bugs.sun.com/view_bug.do?bug_id=8012586 (should become available
in a day or two). Please note that you don't need to commit any changes
with mercurial. You can generate a webrev just for the files that are
modified (webrev can identify them).

best regards,
Anthony
