Re: [aspectj-users] Reusable aspects that have concrete aspects in diffe

[Dmitri Mamrukov <dym@xxxxxxx>]

Nope, not missing import statements. :) I found the cause of this all: 
the abstract pointcut stateChanges(Subject subject) in 
observer.SubjectObserverProtocol.aj was not public. So abstract 
pointcuts should be declared public if one want to implement abstract 
aspects in other packages. Though I observed that if the pointcut 
stateChanges(Subject subject) in observer.SubjectObserverProtocol.aj 
were NOT abstract and NOT public, then the compiler wouldn't complain...

Thanks.
