[aspectwerkz-user] AbstractMethodError under eclipse plugin

Howdy

Im just starting out with aspectwerkz but im having an issue just even 
running a simple test aspect using AspectWerkz 2 (under the eclispe plugin).

Should be pretty simple but keep getting an AbstractMethodError..

any clues.. or am i just being clueless?

thanks

----Class:
package test;
public class TestMain {

	public static void main(String[] args) {
		System.out.println("app started");
		TestMain main = new TestMain();
	}
	
	private String foo;
	
	public TestMain()
	{
		System.out.println("about to set foo");
		foo="bar";
	}
}

----Aspect:


package test;
import org.codehaus.aspectwerkz.joinpoint.JoinPoint;

public class TestAspect {
	
	/**
	 * @After set(String test.TestMain.foo) AND args(foo)
	 */
	public void aspectRun(JoinPoint joinPoint, String foo){
		System.out.println("got something called");
	}
}
