Java 8 & DocLint

[Niclas Hedhman]

So, I have just made a massive commit, which I think only contains the Javadoc changes needed for Qi4j SDK to javadoc compile under JDK8.

See http://blog.joda.org/2014/02/turning-off-doclint-in-jdk-8-javadoc.html and http://stackoverflow.com/questions/22528767/jdk8-and-javadoc-has-become-very-strict if you are not aware of the situation.

I thought that "turn off" isn't the best way forward, so I spent the time to fix it up.

HOWEVER, I get weird exceptions about jacoco (what is that?)

objc[21769]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home/bin/java and /Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

Thanks for taking that time!

Yup, the Jacoco build setup must use the latest Jacoco version available to work with Java 8. From what I remember, the build use the Gradle Jacoco plugin in each module but use the ant task to produce the aggregated coverage report (should be in ~/build.gradle). I'll take a look when I get some time if you don't figure it out.
