Hello. Is it ok to backport http://icedtea.classpath.org/hg/icedtea6/file/589610636e32/patches/openjdk/6967436-6976265-6967434-pisces.patch to 1.7, 1.8, and 1.9? It should fix this: https://bugzilla.redhat.com/show_bug.cgi?id=661554 (it most definitely will eliminate the exception). Regards, Denis.
