EVALUATION The same problem happened to Swing after the recent T&L putback of 5045147. Although their putback revealed this, it wasn't bad code. It simply reveals an incorrect usage of TreeSet. The TreeSet() constructor clearly says that objects used with it must implement Comparable. AWT (and Swing) were using objects that aren't Comparable. Swing fixed this problem, under 6434148, by replacing the affected TreeSets with HashSet.
