I think it looks very good, impressive work!

I'm going to push what we have, because it's good. But keeping this pull request open until we resolve why the @OverRide annotations have gone away?

Pending @OverRide review before close

Hi Andrew,

@OverRide annotation were removed as they were JDK 6 specific (@OverRide on a method implemented from an interface won't compile on JDK5). I forgot to mention that in detailed commit message.

[ALRubinger]

We compile on JDK6, set target to JRE5-compat. So that's fine. :) Would you put 'em back?

[kpiwko]

Yep, I will put them back.

Andrew, @OverRide annotations are back. Please note that I used custom save action in Eclipse, resulting in more @OverRide annotations we had before ;). Now all methods that implement an interface in shrinkwrap-extension-resolver are annotated with an @OverRide annotation.
