Java will hang if a finalizer runs out of memory if finalizer run synchronously

Java will hang if a finalizer runs out of memory if finalizer is run synchronously.

This is probably due to the fix for bug #1255338

If a finalizer is run synchronously due to low memory, and the
finalizer itself allocates memory, it may try to run finalizers again.

The second time will get hung up in the wait loop in runFinalization:

    while (BeingFinalized != NULL) {
        FINALMEQ_WAIT();
     }
