WTF ! while it's maybe a binary compatible change, I haven't take a look to all modified classes to be sure it's not a source compatible change. People had created class that inherits from ArrayList and override clone, while it's not a good practice, there is a lot of code from pre-1.5 days that does exactly that, this change will simply break all those codes.

I guess, as not source compatible for, you think about case A, but not case B? : class SubClass extends JdkApiClass { @Override // case A Object clone() {...} @Override // case B SubClass clone() {...} }
