I've followed that bug with interest. Java on Mac OS X is multi-threaded, so it should show more than 100% processor usage in top / Activity Monitor. In fact, on our PowerPC G5 Xserve, we regularly crapped out the processors at 200% running ZCS.

On a side note, we have experienced random kernel panics since migrating to the Intel Xserve, but they are infrequent and the server reboots automatically.
