> Running a preview on an XML datasource causes a freezing of the gui. The main thread is stuck trying {{SocketInputStream.socketRead0}}, which never returns.
> The jboss log indicates a BlockedException has occurred and only when designer is forcibly terminated does the input stream read get cancelled.
> Discussions over the log indicate ...
> '... a timing issue where the asynch processing thread notifies after the processing thread has been detached and there's no other action that restarts the plan'
> Server log snippet attached.
