> The command relies on _Map.putAll()_ to populate *CatalogBase* when passed into the constructor, but as the javadocs specify at http://docs.oracle.com/javase/6/docs/api/java/util/Map.html#putAll(java.util.Map), this throws an NPE. The constructor requires a guard inside to protect it from null objects being passed as an argument
