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

[Andy Clement <andrew.clement@xxxxxxxxx>]

Hi,

execution() pointcuts take attempt to  match on the declared
signature, your signatures are not declared as '? extends/super' so
the pointcuts don't match.  This would match:

execution(void Simple1.func*(Collection<Simple1+>))

There is a section in the docs (although it is a bit short...):
http://www.eclipse.org/aspectj/doc/next/adk15notebook/generics-inAspectJ5.html#matching-generic-and-parameterized-types-in-pointcut-expressions
"Generic wildcards and signature matching"

cheers
Andy
