Even thought it says 8 in the POM, it doesn=E2=80=99t force you to use =
it. Currently, it looks for the highest JDK version available and use =
it.

I think we should change it to force you to use 8 now since we have used =
JDK 8 features in the code. That way the error message will be much more =
clearer :-)

Ian said that this change is easy to do.
