Hi,
I'm having troubles with
DefaultIoFilterChainBuilder.buildFilterChain(IoFilterChain) that
appears to be called twice with the same filter chain on incoming
connection resulting in the following error trace:
java.lang.IllegalArgumentException: Other filter is using the same

I just tried using the XML you posted but with the EchoProtocolHandler
and I don't get this error. Looking at the code referenced by the stack
trace (SocketAcceptor.java:353) it appears as if the SocketAcceptor's
defaultConfig has been configured with filters as well? If these come
from a DefaultIoFilterChainBuilderFactoryBean the filter names may very
well be the same (the default names are filter0, filter1, etc).
You could try to set a different filterNamePrefix on your
DefaultIoFilterChainBuilderFactoryBean and see if that helps or name
your filters explicitly using IoFilterMapping objects.
