It doesn't look like an exception from Railo itself. Google indicates
it can happen with a number of web apps running on Tomcat, usually at
shutdown. I see issues logged against LifeRay, Hudson and a few other
things. Most people report it happening against Tomcat 4.x. I haven't
seen reports against more recent versions. One bug report indicated
that the line above the wait() call in the Tomcat source says "this
can't happen" which is... unhelpful...
Are you seeing problems with your website? Or are you just worried
about seeing an exception from Tomcat in your log files?
