Description

DbNotificationListener and NotificationListener both depend on AddPartitionEvent.getPartitions() to get their partitions to trigger a message, but this can be null if an AddPartitionEvent was initialized on a PartitionSpec rather than a List<Partition>.

Also, AddPartitionEvent seems to have a duality, where getPartitions() works only if instantiated on a List<Partition>, and getPartitionIterator() works only if instantiated on a PartitionSpec.
