I'm not related to this in any way – so I can't speak for them. That said, the dependency is still mentioned in the Readme.

Provided that there are dependencies like Dojo and that that this was written in a time, when everything claiming seriousness was expected to look Java-ish, I'd guess, it may need a complete rewrite to fit the modern ecosystem. (Disclaimer: I didn't have a closer look at the code.)
