[aspectj-users] Named pointcuts in gerenic aspects

[Jan Hannemann <jan@xxxxxxxxx>]

I'm trying to write a generic abstract aspect containing a named 
pointcut and associated advice:

public abstract aspect GenericAspect<Par1, Par2> {
   abstract pointcut checkpoint(Par1 par1);

   after(Par1 par1): checkpoint(par1) {
       // do something
   }
}

This does not seem to work, regardless of whether the PC is abstract or 
concrete. The compiler (1.3.0.20051220093604, AspectJ 1.5.0) complains:

"incompatible type, expected java.lang.Object found 
BindingTypePattern(TPar1;, 0).  Check the type specified in your pointcut"


Note that this works as an unnamed PC:

public abstract aspect GenericAspect<Par1, Par2> {
   after(Par1 par1): target(par1) { // silly example
       // do something
   }
}

What might be the reason for that?

Thanks,

--Jan
