org.jboss.remoting3.EndpointImpl$ConnectionProviderContextImpl.accept():

public void accept(final ConnectionHandlerFactory connectionHandlerFactory)

{ connectionHandlerFactory.createInstance(new LocalConnectionContext(connectionProviderContext, new ConnectionImpl(EndpointImpl.this, connectionHandlerFactory, this, "client"))); }

creates a ConnectionHandler, but the call to new ConnectionImpl() also creates a ConnectionHandler.
