Review Request : JMC-6139 : java doc missing for JMC Core modules

[Guru]

Hi,

Please review the fix for 
JBS : https://bugs.openjdk.java.net/browse/JMC-6139 <https://bugs.openjdk.java.net/browse/JMC-6139>
Webrev : http://cr.openjdk.java.net/~ghb/JMC-6139/webrev.0/ <http://cr.openjdk.java.net/~ghb/JMC-6139/webrev.0/>

Root cause : Fix for JMC-6108 removed the javadoc generation.
Solution: enable “maven-javadoc-plugin” and generate javadoc for core modules.

Thanks,
Guru
