I have a method that I want to add to the Object class as follows:

boolean Object.olderThan(Object value){
		//System.out.println(val+"OLDER");
		return val;
	}

but I am getting the error message typeNotExposedtoWeaver runtime error. Can anyone provide a detailed tip on how to successfully add a method to the Object class ?

You are trying to weave into the JDK. In general, this is not possible using LTW. The reason is that the weaver itself is written in Java and the weaver must be loaded before weaving can start. In order to be loaded, some portion of the JDK must be loaded as well. These classes that are loaded before the weaver is cannot be woven.

You must use compile time weaving and weave into your tools.jar to create a new one that contains the new byte code.
