Environment:
AspectJ 1.6.0
JDK 6u10
Background info:
I've coded an Aspect that would run a particular method a specific number of times. I've created an annotation that can be used to annotate any method that you want to run multiple times
RunMultipleAspectTestApp is the driver class. When I set the RunMultiple.counter to something less than 900, it works great.
But when I raise it to 1000 or more, I get a java.lang.StackOverflow error. I googled and saw that StackOverFlow error occur
due to infinite recursion as noted in this document: http://www.eclipse.org/aspectj/doc/released/faq.html#q:infiniterecursion
Do I have my pointcut defined incorrectly? Could someone please help me with the pointcut definition for the "repeat" advice?

The RunMultipleAspect has a repeat (After) advice which is called on any method annotated with the RunMultiple annotation. RunMultipleAspect
also intercepts object construction (AfterReturning) and caches the object that is created so it can reuse the object in the repeat advice.
The repeat advice looks up the RunMultiple.counter value and then invokes the object method if 'RunMultipleAspect.count < RunMultiple.counter'

The RunMultipleAspect has a repeat (After) advice which is called on any method annotated with the RunMultiple annotation. RunMultipleAspect
also intercepts object construction (AfterReturning) and caches the object that is created so it can reuse the object in the repeat advice.
The repeat advice looks up the RunMultiple.counter value and then invokes the object method if 'RunMultipleAspect.count < RunMultiple.counter'
