I get the impression that someone doesn't like Java and used chat gpt to create a one-to-one typescript port.

I dislike Java as much as the next guy, but I believe the true value of tools (and this tool in particular) is in the embedded wisdom and experience of their creators/Terrence Parr. Just generating a functionally equivalent port doesn't add much value.

That said, that's just a first impression, I have no idea what motivated this fork
