Java generics, explanation needed

There are several simple test-case classes:

public interface ListCriteria<T> {
  // some stuff here
}

public class UserListCriteria implements ListCriteria<User> {
 // implementation
}

public interface Editor<T> {
  // sample method 1
  List<T> listObjectsTest1(ListCriteria<T> criteria);
  // sample method 2
  <L extends ListCriteria<T>> List<T> listObjectsTest2(L criteria);
}

And there is an implementation of Editor which Java thinks it does not provide necessary implementation for both sample methods:

public class UserEditor implements Editor<User> {

  @Override
  public List<User> listObjectsTest1(UserListCriteria criteria) {
    //
  }

  @Override
  public List<User> listObjectsTest2(UserListCriteria criteria) {
    //
  }
}

Both method implementations are wrong. The question is why. Especially for the latter method. Sure I could do interface Editor<T, L extends ListCriteria<T>>, and that would solve the issue, but I don't want to, I want to understand why I can't use method-level generics here.
