maybe backwards compatibility?

  How exactly adding map() is not backwards compatible?..
  • xendo 9y ago
    Adding methods to non-final classes is always incompatoble. If you had your own implementation of list and its interface suddenly requires new method, how should it behave?
    • riku_iki 9y ago
      map() in AbstractCollection will obviously have some default implementation, which will be used by all child classes.
