I have enabled cometSupport in the domain.xml (the jmaki-comet demo works well!), but I keep running into the error below. I can't figure out why it is being thrown, as the thread invoking the methods all seem to be the same as well.

Right now the code is pretty rough and most likely incorrect, but it is based on the grizzly+comet demo (http://docs.sun.com/app/docs/doc/820-4496/ggrgt?a=view) and should be working a bit better than it is now. See the error below.
