Morning,
We've just put together our first HttpCore-based server and we're
intermittently seeing an exception in our logs which is causing the
entire server to shutdown.
INFO com.acmecorp.proj.http.HttpSSLServer: Connection open:

Can you advise if this is related to the item discussed in
http://hc.apache.org/httpcomponents-core-4.0.1/tutorial/html/nio.html#d0e1240,
or is it likely to be an unrelated issue with our code? The NPE
suggests to me that it's more likely to be our code.
Thanks,
Sam
