I think it works well if you look at the log here
If you approach the actual opencode and test the lsp server functionality
Error: LSP server 'jdtls' is configured but NOT INSTALLED This error has occurred and the lsp server function is not available
This phenomenon is located in the lsp area on the right
If jdtls is shown to be enabled, it will happen the same.

I'm having the same problem—Java's LSP service isn't working, and I've been looking into it for two days.
