In one of my builds (run via Hudson), on only one of the multiple slaves it
could run on, I'm seeing the below error. I've had the machine rebooted, but
it keeps coming back. The other slaves this build runs on are configured
identically to this one, and, as I mentioned, they have no problems. Any
idea what I should be looking for to have caused this? (I'm trying this list
since the actual error is popping up in the Maven execution - I do also seem
to get it from the command-line as well).
