Re: [ajdt-dev] AspectJ 1.6.4 bug on getParameterNames

[Simone Gianni <simoneg@xxxxxxxxxx>]

Hi Andrew,
sorry for being vague but I was a bit in a hurry switching back to 1.6.3 :D

In this snippet :

       MethodSignature sig = 
(MethodSignature)thisJoinPointStaticPart.getSignature();       
       Object[] args = thisJoinPoint.getArgs();
       Stirng[] names =  sig.getParameterNames());

I have names.length == 1 and args.length == 0. In fact, the join point 
method has zero arguments, so I suppose it is getParameterNames that is 
returning wrong data. getParameterTypes seems to be fine however.

I think we are talking about org.aspectj.lang.reflect.CodeSignature methods.
