- open this class in a java editor:

package override.test;
public class A {
	<T, U extends T> void m(T t, U u) { }
}
class B extends A {
//	@Override
	<X, Y extends X> void m(X t, U u) { }
}

- open ASTView and focus on the 'X' in 'Y extends X'
- boom:
Error 2005-08-15 12:04:56.18 Could not set AST view input
