Okay. Here is a concrete example with nb-javac enabled.

I created two projects. SlowCodeCompleteMaven, and SlowCodeCompleteAnt. They 
contain identical classes.

In SlowCodeCompleteMaven, I place the caret inside {{MyClass}} after 
{{firstMethod()}} and before the closing brace. I then hit CTRL+SPACE. The IDE 
takes 7 seconds to respond. I get identical timing with nb-javac disabled.
If I perform the same operation for an Ant project, the response is 
instantaneous.

I am attaching these projects to this issue. Please take a moment to confirm 
whether you can reproduce the problem on your end. Thank you.

> Say I'm in a class that has a field {{singletonScope}} where this class is 
> defined within the same Maven module.
> I type {{singletonScope.}} then wait for auto-complete to suggest possible 
> methods. Code-complete takes roughly 10 seconds to come back.
> This is reproducible 100% of the time.
> Expected behavior: Code-complete should complete within 300ms or less.
