LSP doesn't start (server reset the connection)

Relevance Confirmation

• I confirmed that this is not an issue with the Eclipse JDT Language Server itself

What happened?

The language server fails to start. The following error message is provided:

Language server java:

What did you expect to happen?

I expected the language server to start.

@Mibanfi this is an issue with JDTLS cache. Delete the cache and restart the LSP.

An issue related to this is tracked under #135.
