Supun Kamburugamuva updated SYNAPSE-592:
----------------------------------------

    Attachment: SYNAPSE-592.patch

Attaching a simple fix that checks this buffer and if it is null close the \
connection.

> If a url with a space submitted to the synapse, nhttp transport goes in to an \
>                 infinite loop

> 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. 2009-10-13 15:07:46,671 [-] [http-Listener I/O \
