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.

I see lots of problems in that code.

I don't consider lack of type aliases as one of them.
