Bug 101261 [type hierarchy] overriding a method from context menu > Source is not 5.0 aware
N20050622-0010 There's a hidden feature in the type hierarchy, that allows you to select a type XY and an inherited method, open the context menu and select Source > Override in 'XY'. This action has not been updated for 5.0 and creates a wrong method stub when generics are involved, e.g. here: public class Top<E> { public void method(E e) { } } class XY<ELEMENT> extends Top<ELEMENT> { } It creates (wrong formatting, 'E' instead of 'ELEMENT'): public void method(E e) { // TODO Auto-generated method stub super.method(e); } I'd suggest to drop this action, since the Override/Implement Methods... dialog and content assist do better jobs.
