Description Raksha Vasisht CLA 2011-06-14 02:58:19 EDT 
BETA_JAVA7

Test:
-----
List<Integer> m() {
    	HashMap<String, ArrayList<Integer>> field= new HashMap<>();
    	return  (ArrayList<?>)field.get(0);		
}

Hover on the warning on field.get(0), it shows a message :

Type mismatch: cannot convert from ArrayList<capture#1-of ?> to List<Integer>

It does not make sense. Should show a more meaningful message . The message comes from jdt-core, need to investigate.

This has always been the case ever since 1.5 came out. Even javac has the same error message.
Comment 2 Markus Keller CLA 2011-06-15 10:57:19 EDT 
It's an error, not a warning, and it's not on "field.get(0)". It's on the whole CastExpression "(ArrayList<?>)field.get(0)", and there it is fine.

Verified.
