Line: int currentCount = GrouperUtil.intValue(debugMap.get(countKey), 0);

The parameter numberOfCalls is long, but currentCount is read as int. Then on the next line:
 debugMap.put(countKey, currentCount + numberOfCalls);
 
This expression currentCount + numberOfCalls promotes to long (since numberOfCalls is long), so the first time it works fine. But on the second call, debugMap.get(countKey) returns a Long object, and GrouperUtil.intValue() is being asked to convert a Long to int — which could truncate if the value exceeds Integer.MAX_VALUE.

It's not a practical problem (you'd need billions of API calls in a single provisioner run to overflow), but it's inconsistent — currentCount should be long using GrouperUtil.longValue() to match the type of numberOfCalls, just like currentMillis on the next line correctly uses longValue. It's a minor code quality issue, not a real bug.
