Steps to Reproduce

Open a java file.

Expected Result

I use treesitter for syntax highlighting and it works fine:

Actual Result

As soon as jdtls started, the highlights become ... much more boring:

Most highlights have the same color. The syntax has improved, I like how the imports separate package names from class names. However, I don't find any documentation on how to configure these.

I understand, if this is not in the scope of this plugin. Still, if you have any idea where I can find docs - any help appreciated!

This is due to LSP semantic tokens which was recently merged in neovim. See :h lsp-semantic_tokens and https://github.com/neovim/neovim/pull/21100

You could tune your color scheme to support the highlight groups. In latest neovim master you can use the :Inspect command to get information about what groups are used by a word/expression under the cursor:
