What about java?

Can I make it usable for java?

I think it is doable, just use for example eclim and set it to use autocomplete, and then just use exactly same trigger regex as JavaScript uses:

let g:completor_java_omni_trigger = '\w+$|[\w\)\]\}\\\'\"]+\.\w*$'

Do not have time to test it, but it should work.

E15: Invalid expression: '\w+$|[\w)]}\'"]+.\w*$' @deathbeam not working rather throwing an error
