Created a separate branch on my repo for this fix, and submitted a new pull request.

Stevo Slavić commented

Build passes well without change with Java 1.6 (jre-1.6.0-openjdk.x86_64) javadoc, so this is Java 1.7 javadoc specific. Nevertheless, IMO it should be fixed.

Fixed, see linked pull request for details.
