> I've submitted an invalid url (a url with a space) to synapse. When this
> happens NIO transport goes to an infinite loop. It shows the following
> exception repeatedly. The reason for this is a Null point exception.
> In case of HTTP error, synapse ServerHandler doesn't get called for the
> input. But the outputready method of the ServerHandler is called. In the
> output ready method we check a output buffer variable. But since the input is
> not given to syanpse this buffer is not set. Resulting in the null point.
> I've done a simple fix to avoid this. But I think this should be handled in
> the HTTP Core Nio level. It shouldn't call the output ready method when there
> is an error.
