Because Jigsaw uses persistent connections for HTTP (ie m,ultiple
requests can use the same connection). A connection can be closed
either by the server or by the broswer.

In the above case, your browser did close the connection, so Jigsaw
got that exception (and handled it properly). All this is compliant to
the specs, again, the bug is that you saw the trace...
