URL: https://github.com/apache/geode/pull/5722


   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);
     }
   }
   ```
   We ultimately decided that if the buckets were not created at the time the 
value of `serials` is generated, there is no need to worry about their profiles 
getting deleted later.  To avoid the `ArrayIndexOutOfBoundsException`, 
`getBucketSerials()` was modified to return an array of `ILLEGAL_SERIAL` values 
if the buckets had not been created yet.
