Can you tell us more about how you ran the second server? Is this an independent installation or is it the same installation as your first server just starting with a different port?
Because this is very strange. It half feels like there are conflicting jars somewhere in your path, but that's a guess. This really shouldn't be happening unless something _did_ change that doesn't seem important but is.... And does this only happen when both servers are running? If you turn the second one off and this still occurs, it _really_ sounds like clashing jar files....
