    GroupLayout is introduced in java 1.6 , mac os 10.4 ,10.5 still uses java 1.5 by default. Even when 1.6 is installed you have to manually set os x to use 1.6. Or if you are the developer of the application, there are separate jars for GroupLayout. you can bundle that with your application and use GroupLayout with java 1.5.
