Weld throws NPE in Google App Engine

Details

    Description

      Weld is throwing the following NPE in Google App Engine - this is not happening on the first page render, rather on a refresh (Pete mentioned it is probably a serialization issue). If you delete the session cookie and refresh the page again the exception is not thrown.
