Re: [aspectj-users] super and extends in generic pointcuts

[Andy Clement <andrew.clement@xxxxxxxxx>]

Resending as apparently my first email didn't get through...

===
You fixed the p11 case by making a method that had the same signature
as the pointcut.  Do the same for the other pointcut:

 pointcut p12() : execution (void Simple1.func10(Collection<? super
Interface1>));

Something like:

public void func10(Collection<? super Interface1> s){ }

cheers,
Andy
