> When certain types of errors are raised while the network server is processing a client
request, the server is left in a semi-degraded state. The problem this issue is concerned
with, is that the client socket is kept open even though the server in a kind of degraded
state (server JVM still alive). This causes the client to hang, until the server JVM is killed,
in a read-call on the socket.
> I'm able to reproduce this with an OOME being raised on the server.
> In my opinion, hanging when there is no chance of progression is bad behavior. Furthermore,
it causes trouble for automated testing.
