> The TopologyMangerImport class uses the MultiMap (Map<String, Set<T>>). The
operations on the MultiMap itself are thread safe (by means of synchronised keyword), however
in some cases the Set<T> value is obtained and iterated over, without holding the right
mutex. As a result you may see ConcurrentModificationExceptions.
