The fact we still don't have a decent Java language server is one of my canaries for the fact that LLMs still, generally speaking, can't ship. There is undeniably demand for this sort of thing, but nobody is coming to meet it. (jdtls, bless it for trying, is just not good)
That's just a wrapper for jdtls. I mean it works on some projects, but fails on many gradle builds and is basically just running the Eclipse IDE headlessly.
there's a lot of stuff coming in the PHP world, between phpactor that's been there for a while, mago that wants to make a lsp and this that's great having choice. But I'm not sure I'll be able to let go phpstorm even though its bugging me more and more every day it's just too good
And speaking on llm and lsp. The new PHP lsp PHPantom (with help of llms) is approaching jetbrains offering fast.
This is probably the one contender:

and it kinda works, but it's also a bit lacking.
