I saw this sentence, but I decided it was irrelevant, or at least
didn't tell the whole story: it specifies the signature of a
method execution join point, but it doesn't specify how a method
execution pointcut designator signature pattern matches it.

I think this is wrong: thisJoinPoint.getSignature().getDeclaringType()
returns A2.  Even if it were A1, it wouldn't explain why both
pointcuts (with different qualifying types) contain the same join
point.

As far as I know, the whole declaration/definition distinction is just
left over from C and doesn't exist in the Java language spec.  A
class declaration contains member declarations; a class type contains
declared and inherited members.
