JFYI: Eglot, published in GNU ELPA, is a an adequate LSP client, and it 
integrates with Company (for completion) and Flymake (to show syntax 
errors, missing imports, etc). Most of the time the user just needs to 
install a corresponding language server program.

It doesn't offer as comprehensive set of refactorings as the 
contemporary Java IDEs, but it does support some.

See above. There are language servers for Java and C++.

I think we'll get there after we figure out how to bundle some ELPA 
packages together with the core for releases.
