There is a newer version: 2.14.0.5032

Why is this an issue?
Loggers should be:

   private: not accessible outside of their parent classes. If another class needs to log something, it should instantiate its own
  logger. 
   static: not dependent on an instance of a class (an object). When logging something, contextual information can of course be
  provided in the messages but the logger should be created at class level to prevent creating a logger along with each object. 
   const: created once and only once per class. 

Noncompliant code example
With the default regular expression LOG(?:GER)?:
public const logger:ILogger = LogUtil.getLogger(MyClass);

Compliant solution
private static const LOG:ILogger = LogUtil.getLogger(MyClass);
