Hi Stanislav.

I've proposed this fix for the bug:
http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2011-June/014574.html

I tested it, and it does fix the compilation problem, but as Andrew Haley rightly pointed out, such compiler changes are very dangerous. I also submitted a patch to the discovery project that works around the compiler bug, and hopefully they will include it in their project.
Comment 2 Denis Lila 2011-06-01 20:52:01 UTC 
Hi again.

commons-discovery has accepted my patch, so I am closing this as wont-fix for now. If this compilation problem comes up with some other project, we can reconsider the backport.
