Since today the maven builds in hudson started failing with this stacktrace:

I have seen this a few times on my Hudson build slaves. I'm not sure what the root cause is, but deleting the workspace and letting Hudson rebuild it and in particular re-download java seemed to work.
Of course, if this is happening on the master node, that won't help you much.
