Neovim version (nvim -v)

NVIM v0.11.5

Operating system/version

archlinux 6.18.2

Describe the bug

I'm encountering errors when configuring nvim-java with nvim-lspconfig for Java support. The plugin fails because of a missing 'get_arch' function and an incomplete URL configuration table that does not support common architectures like x86_64.

Steps To Reproduce

1. Add require('java').setup() and require('lspconfig').jdtls.setup({}) to init.lua.
2. Open a Java file (.java) in Neovim to trigger LSP loading.
3. Observe errors in :messages or Neovim startup.

Expected Behavior

nvim-java should detect the system architecture and successfully resolve download URLs for Java tools, allowing jdtls to work without any errors.
