Hmm... Not really sure what the actual cause is. Can you wireshark the
interaction and see what did get written? From the stack trace, it looks
like a request came in, it was processed, a response was started to be
written out. During writing the response, some exception occurred from
Jetty (no idea why... maybe client closed the stream or something). At
that point, the fault chain was started. However, since at least part of
the response was written out already, you get that exception. Basically,
when streaming responses, it's nearly impossible to recover from exceptions.
That's the stack trace you are seeing.
I'm NOT sure what jetty is doing to cause the NPE in Jetty. No idea on
that. :-(
