Weird exception starting up HornetQ today

[postmaxin]

I had to restart a hung hornetq process today, and upon restart, I got this stack trace. I haven't seen it before. Any ideas what's up? Is the thread that is now running safe or should I restart it again?

What version?

I haven't seen it, but I had done some fixes after 2.2.5 (next version).

I was using the build you asked me to use last month (Branch_2_2_EAP@r11262). This is the first time I've seen this particular error. Is it worth rebuilding with something newer?

[clebert.suconic]

Do you still have the data?

[postmaxin]

If you mean do I still have the contents of the persistent message store, no -- a few thousand consumers would have reconnected immediatley on restart.
