[ews.eclipse.technology.aspectj] Trying to pick up annotations on args

[dan@xxxxxxxxxxxxxxxxxxxxxxxx (Dan Haywood)]

Okay, guys, tell me what I'm doing wrong.

I have:
public class MandatoryParamFixture {
	public void withMandatoryParam(@Mandatory String param) { }
}

with:
public aspect MandatoryParamAspect {
	pointcut executeArg1(String arg) : 
		(execution(new(@Mandatory Object+, ..)) || 
		 execution(* *(@Mandatory Object+, ..))    ) && 
		args(arg, ..);
	
	before(Object arg): executeArg1(arg) { 
		if (arg == null) {
			throw new IllegalArgumentException("Mandatory!");
		}
	}
}
You get the idea?  However, the executeArg1 pointcut doesn't match the 
method in my fixture.

I've obviously misunderstood this pointcut pattern, can anyone set me 
straight?

Thanks
Dan
