Description
I am using ProtocolCodecSession for some unit testing. Somewhere in the code I am testing, getService() is called and it returns null. So I have to check this value to avoid the NPE.
This is because DummySession still has an IoService member which is not used any more (moved to AbstractIoSession?). Which is why I am reporting this bug, I wouldn't otherwise.
2.0.0 is not impacted.
