It's a pity that it doesn't support Java, it's more or less also a C family language (if one puts Objective-C and C++ in same bucket as pure C).

Or maybe someone tried it in Java?

I would really like to have better support for Java in vim(just editing and code completion, I don't debugger in vim). Do you know some useful plugins for this? I tried several (I don't remember the names) and I'm back to old omnicomplete that's in vim.
