@Shougo can you to participate?

[Shougo]

@J-Liu If you get the errors by <C-X><C-O>, it is not related to deoplete. It just vim-javacomplete2 error.

[artur-shaik]

@J-Liu leave just vim-javacomplete2 plugin in your config and call completion on <C-x><C-o>, please.

[J-Liu]

Sorry, it was my fault, I used JDK 9.0.1 instead of 8.x. vim-javacomplete2 by deoplete.nvim is perfectly working now.

deoplete-jedi is not that good so I used completor.vim replaced.

Thank you @artur-shaik @Shougo all for you all are so kindly.
