[ JDK VERSION : 1.7.7 ]

There's a circularity where a hint suggests a refactoring that leads you to a 
condition where another hint suggests a refactoring that brings you back to 
initial condition.

No funky import rules (default + grouping).

If you import a static nested class (which you use in your code) and you also 
statically star-import the parent class, the hint shows up saying that it's 
"never used". If you refactor, it gets removed, but then it says it doesn't 
adhere to import rules. If you refactor again, there you are at square one.

Please see attached screenshots for a much clearer visual explanation.
