Neovim version (nvim -v)

v0.11.0

Operating system/version

MacOS 15.4
Debian 12

Describe the bug

Using nvim-java no lsp document symbol is found. By manually configuring nvim-jdtls I noticed the lsp does provide document symbols in that configuration.

I tinkered a bit with nvim-java-core and removing this line makes lsp document symbols appear:

nvim-java-core/lua/java-core/ls/servers/jdtls/config.lua

Line 14 in 401bf76

clientDocumentSymbolProvider = true,

I'm not sure what clientDocumentSymbolProvider = true does though so I don't know what the full consequences of removing that line are.

Steps To Reproduce

1. Install nvim-java.
2. Open a Java file.
3. Try to open document symbols, e.g. through fzf-lua's builtin lsp_document_symbols.

No lsp document symbol will appear.

Expected Behavior

Lsp document symbols are expected to be found and displayed.

Removing the above mentioned line leads to the expected behaviour but I don't know of possible side-effects as I don't fully understand what the line does.
