Julien Vermillard commented on DIRMINA-47:
------------------------------------------

what are you exactly doing for closing and creating new ProtocolSession ?  The ProtocolSession
with NULL selection keys is the newly opened one or the closed one ?

and creating new ones which may have something to do with it.  I also use the DemuxingProtocolCodecFactory
to manage my protocol messages as well as their encoding and decoding.

 I'm still not sure what causes it but everything appears to still work if I put a try/catch
for a NullPointerException in the SocketIoProcessor around line 496
