Fixed javadoc errors.

If you clone the nailgun repository, it builds just fine. However, if
you try to use this version of nailgun with scalafmt [1], it doesn't
actually work [2]. In [2], they suggest building the nailgun-all-0.9.1
tag. But, this tag doesn't build because of javadoc errors. This commit
fixes those errors so that the code builds again.
