Not just HashMap:

"java.util.GregorianCalendar, java.util.Hashtable, java.util.HashSet,
java.util.HashMap, java.util.ArrayList, java.util.LinkedList,
java.util.LinkedHashMap, java.util.LinkedHashSet, java.util.TreeSet,
java.util.TreeMap, java.util.Vector"

I suppose the check is pushing me to pass/return custom data objects
that implement Java-specific data structures behind the scenes? I
can't see how you would write meaningful code without eventually using
one of the listed data structures, but I can see vaguely how it would
be beneficial to wrapper the implementation of these data structures.
