Ahm. I did not knew BSD 2-clause has to be in each source file. Is it really so?

I actually don't mind it, but, frankly, seems an absolute overkill to me. Probably the maven-license plugin would be handy here. But it's effort...

Would you consider helping by making a PR which would integrate the maven-license-plugin into the build? Then we'll have solved it once and for all and I could replicate the solution in other projects as well.
