I'm seeing the following stack trace from my Restlet 2.1.1 client application
when talking to my Restlet 2.1.1 server running on the GAE SDK development
server. It is intermittent (sometimes the client app runs to completion), and
happens on different calls.
Exception in thread "main" Communication Error (1001) - The connector failed to
complete the communication with the server

When I crank logging up to FINEST, this is the end of the server stdout:

The last INFO message comes out a second or two after the client crashes. The
two JettyLogger debug FINE EOF messages are consistently the last messages when
the client crashes.
Note that the server doesn't crash; it continues running.
