Use other World Wind GitHub repository?

There seems to be some confusion in the community over the difference between this repo and the one at https://github.com/NASAWorldWind/WorldWindJava.

Based on the activity here (i.e. none for many years) and that the http://worldwind.arc.nasa.gov/java/ site points at the other github repo, i'm going to assume this repo is dead and should be ignored.
