Perfect!

I've copied java@gcc.gnu.org just in case somebody recognizes the
failure you've describe below.  However, in general I would say that the
focus these days is on the coming 3.1 release (in ~2 weeks?).  I believe
there were a number of JNI bugs fixed between 3.0.x and 3.1, and fixes
are unlikely to be rolled back into the 3.0.x tools.  I strongly
recommend downloading, building and installing a 3.1 snapshot.

Thanks,

AG
