the license header presence? well the thing is that I took some code from the: https://github.com/typekpb/arquillian-examples/tree/master/xa 

not sure about licensing, but as it had the license, I better let it there.
Is there any better way to proceed here? I don't think I can just remove it. Anyway we would not deliver this code, I think. Maybe we should just add a note, that we have there some APL 2.0 code present. Not an expert on license though.
