Exception in lsp4j if Eclipse is closing

[vogella]

I'm building an tutorial for users to implement their own LSP server using lsp4J. Works fine and I hope it will help with the adaption of lsp4j. But if the runtime IDE shuts down I get an exception. I think I have seen that also in other LSP implementation and they implemented a fix which AFAICS is not documented.

Is their some information how to prevent this exception?

Hi Lars,

Thank you very much for your effort with creating the tutorial! It sounds great, and is really appreciated.

Please make sure that cancel(true) is called on the future returned by Launcher.startListening, as has been documented in #777.

The issue looks very similar to #585 and #770.

HTH :-)
