Config

That's the config basically.

Thank you for reporting this.
I was indeed able to reproduce the issue.
However, I am not sure that this bug has anything to do with nixvim. I will then be closing this.
If you find any lua code that is wrong or missing in your generated init.lua, please feel free to re-open this issue.
Also, if you have access to a classic (non-nix) neovim setup, it could be nice to try reproducing this behavior there.

Also, maybe you could you try using nvim-jdtls instead. This is what people seem to recommend.

Some people seem to encounter this error on a "normal" neovim setup:

I remember reporting this in the original pr: #417. It was annoying but I think the server would still work. I ended up switching to nvim-jdtls although I don't write java anymore so I haven't really used it much.
