 Never written things like this?
      private final HashMap<Integer, ArrowLabel>
         SatLabels = new HashMap<Integer, ArrowLabel>();

I would write:
private final Map<Integer, ArrowLabel> satLabels = new HashMap<Integer, ArrowLabel>();
to follow OO best practice and Java coding convention.
But I think it is good code.
It is very clear what it is. All Java developers know what Map
and HashMap are.
Introducing application specific aliases for Map<Integer, ArrowLabel>
and HashMap<Integer, ArrowLabel> would make the code less readable.

Or this?
      return
         new Iterable<Map<String, String>>()
           {
             public Iterator<Map<String, String>> iterator()
               {
                 return
                     new ResultMapIterator
                       (
                         Resolver.query
                           (
                             /*uri =*/ ProviderUri,
                             /*projection =*/ FieldNames,
                             /*selection =*/ Selection,
                             /*selectionArgs =*/ SelectionArgs,
                             /*sortOrder =*/ SortOrder
                           ),
                         FieldNames
                       );
               } /*iterator*/
           } /*Iterable*/;

I see lots of problems in that code.
I don't consider lack of type aliases as one of them.
