## Q&A
* Yes, I tried minimal .vimrc configuraion.
* Yes, I have enabled logs with `JCdebugEnableLogs` and can put here content of `JCdebugGetLogContent` command, if you need.
* Even, if you wish, I can set `g:JavaComplete_JavaviDebug` to `1`, than set `g:JavaComplete_JavaviLogfileDirectory`, and put here server logs, too.

This was a PEBKAC of the first order. I had the wrong python configured in neovim config.
