The exception below is thrown when using the web service test page. Try using the List Categories or the login, although I believe all will cause this. This may be an integration issue with EAP, as I do not remember this with seam 2.0.3.CR1 testing.

After this happens the page seems to freeze up and further requests stop firing.
