Can you do:
(toggle-debug-on-error)
(setq lsp-print-io t)
(setq dap-print-io t)and then after retrying paste the content of *messages* buffer and the error callstack?

Can you paste the content of the messages buffer as well?
I believe that the jdt server is not configured with the debug extension, I suspect that you are probably using stock jdt instead of jdt eclipse che one you can fix that by making sure that you are using latest LSP Java and calling lsp-java-update-server
Also, please delete the part in the config section, it is overriding the default java function with the demo one. I will update the readme to make that clear.

Ok, that got me a bit further: M-x lsp-java-update-server. It indeed solves the error described in my original issue description.
I will continue tomorrow, would be awesome to get a good Java debugger in Emacs again (haven't had that since jdibug and dap-java looks even better than jdibug was.

I will update the readme and I will change the code to raise an error if the server is not configured correctly, since lsp-mode is not doing that. Meanwhile update the dap-mode with today's version because l have reverted wrongly submitted cl. If you hit any issue feel free to ping me.
