--- Comment #15 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-11-29 15:36:53 UTC --- Frankly, additional examples which are neither self-contained nor minimized don't help that much. That said, this is a regression and we have already a minimized snippet, thus we are set. When the bug will be closed, please double check that the fix works for your code too, thanks!
