[~jlahoda] I verified the PR. It is even faster than the original patch
(probably because you removed `println()`). Performance is now comparable to
non-Maven projects (2x slower but the absolute time is low). Thank you!

[~jlahoda] Regarding the diff, I am seeing the same directories getting scanned
over and over again (specifically, I am surprised the same entries show up
consecutively). Is this expected? I've attached messages.log for your review.
(UPDATE: I just noticed tens of thousands of other entries in messages.log.1,
messages.log.2. This could definitely be useful to optimize away.)
Also, I am not aware of any side-effects of this patch. What kind of problems
have you run across?

I figured out the difference.
"ant tryme" uses JDK 8. It turns out this bug is only reproducible in JDK 9. I
tried taking the Jenkins build I had been using, downgrading to JDK 8 and sure
enough the bug is gone. (The splash screen looks different for JDK 8 and JDK 9
as well)
Is there a way for me to get "ant tryme" to use JDK 9? I tried setting
"nbjdk.home" inside user.build.properties but it keeps on complaining the path
I am providing is not a valid JDK installation (which it is).

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.
