FYI.  AWT creates a number of loggers  (see 
http://bugs.sun.com/view_bug.do?bug_id=6880089)

Running a simple Framer application (awt helloworld) with JDK 7 b70 
creates 79 loggers on solaris-i586 and 34 loggers on windows-i586.  
SwingSet2 creates a total of 85 loggers including a few non-awt ones on 
solaris-i586 and 35 on windows-i586).
