Eclipse Code Actions are no-ops.

Information

VIM version

VIM - Vi IMproved 9.1 (2024 Jan 02, compiled Jan 02 2024 15:51:11)
macOS version - arm64

Operating System: Mac OS Sonoma 14.2.1 (23C71).

What went wrong

Using eclipse.jdt.ls Code Actions seem to be no-ops.

The LSP itself works, as it is able to complete identifiers and even add the missing imports for said identifiers.

Using eclipse.jdt.ls worked using Doom Emacs, including Code Actions.

Reproducing the bug

1. Install vim
2. Clone https://github.com/eclipse-jdtls/eclipse.jdt.ls.git to ~/opt/eclipse.jdt.ls
3. cd ~/opt/eclipse.jdt.ls && ./mvnw verify -Dskip-tests=true
4. Configure vim/ALE: ` let g:ale_linters = {'java': ['eclipselsp'] }``
