Bug 82940 [quick fix] Missing sensible conversion suggestion
For this code > % cat Test.java import java.util.Collections; import java.util.List; public class Test { interface Wrapper { int doit(); } private static final List<Wrapper> STD_WRAPPERS = Collections.singletonList ((Wrapper)new Wrapper() { public int doit() { return 0; } }); private static final List<Wrapper> STD_WRAPPERS2 = Collections.singletonList (new Wrapper() { public int doit() { return 0; } }); } The value passed Collections.singletonList is actually of the right type so a sensible conversion would be to put in the cast (see the difference between the 2 statics). The current quick fixes offered assume the type being assigned to is wrong (when infact it is right). A useful quick fix would be to cast the parameter to the right type to give the left type (this would help with any 1 arg method of the form X<T> method(T)
