Motivation:
750d235 did introduce a change in ApplicationProtocolNegotiationHandler that let the handler buffer all inbound data until the SSL handshake was completed. Due of this change a user might get buffer data forever if the SslHandler is not in the pipeline but the ApplicationProtocolNegotiationHandler was added. We should better guard the user against this "missconfiguration" of the ChannelPipeline.
Modifications:
- Remove the ApplicationProtocolNegotiationHandler when no SslHandler is present when the first message was received
- Add unit test
Result:
No possible that we buffer forever
