GORA-501 Fix Javadoc for JDK1.8

[djkevincr]

Seems like there are many javadoc related issues are still there in the code base. Will work on the rest once got some time. :) Also I have excluded generating javadocs for generated class packages.

Thank you for marking the exclusion in the Javadoc @djkevincr
+1 in favour of merging into master :)

[lewismc]

Please merge into master @djkevincr

@lewismc Please note I have excluded only for goraci and tutorial generated packages. So there are many javadoc issues left in other packages as well. How do we proceed with this? Ignore all doclint warnings? ( -Xdoclint:none option ) Anyway I can work on fixing the rest.

I think your patch fixes the error's which lead to the build failing. The remaining Javadoc issues relate to warning's... which for the sake of getting the build back to stable are acceptable for the time being. Can you please merge this patch into master if you get a chance? I've just pulled it locally and mvn javadoc:aggregate builds well.

+1 will merge now
