ArrayIndexOutOfBoundsException may be thrown in RegionAdvisor.processProfilesQueuedDuringInitialization

If RegionAdvisor.buckets == null at the time the value of serials is generated, an ArrayIndexOutOfBoundsException may be thrown in RegionAdvisor.processProfilesQueuedDuringInitialization if buckets have been initialized at that point.

Code where ArrayIndexOutOfBoundsException might be thrown in RegionAdvisor.processProfilesQueuedDuringInitialization():

for (int i = 0; i < buckets.length; i++) {
  BucketAdvisor ba = buckets[i].getBucketAdvisor();
  int serial = qbp.serials[i]; <<< Exception thrown here
  if (serial != ILLEGAL_SERIAL) {
    ba.removeIdWithSerial(qbp.memberId, serial, qbp.destroyed);
  }
}
