Hi,
When I met an EOFException at the TCPNIOTransportFilter, I saw some strange
filter chainings.
I have two TCPNIOTransports.
1. Custom client: it has only two filters(TransportFilter -->
MyCustomFilter)
2. HttpServer using AJP protocol: it maybe has two more
filters(TransportFilter --> httpServerCodecFilter --> IdleTimeoutFilter -->
...)
First, HttpServer received AJP packets then the specific HttpHandler called
the custom API with the custom client.
If the http server met EOFException, the following exception occurred. I
replaced real IP and domain into ${http_server_IP},${custom_server_domain}
and ${custom_server_IP}.

===
I don't know whether the thread of stack traces is same or not. But I know
the custom client has only two filter chains but it seems that it tries to
refer to http filters.
I think maybe current FilterChainContext or internalContext was wrong. In
the last exception, peerSocketAddress was correct but DefaultFilterChain
tried to get index 6 and you can see a NPE during getting getFilterChain()
in FilterChainContext.
Unfortunately, it is not easy to reproduce it. And I used grizzly version
v2.3.13.
Could I get some hints about this issue?
Thanks!
