Package: openjdk-6-jre
Version: 6b16-4
Severity: grave
Justification: renders package unusable
When using cacao (icedtea-6-jre-cacao 6b16-4) to run ant I am getting the
following
intermittent assertion failure:
java: lock.c:801: lock_inflate: Assertion `((lockword) & ~(((1 << 8) - 1) <<
1)) == t->thinlock' failed.
Note that this is intermittent -- it fails only about half the time.
The hardware is a Cavium Octeon with 12 MIPS64R2 CPUs. The vendor supplies
a port of Debian Etch that has the following patch to glibc that may be apropos:
glibc-linuxthreads was modified to preform the proper "sync"
instructions during locks and atomic operations.
