Not sure I follow. What exactly can the compiler check? The API for UnmodifiableSet is basically the same as the API for Set. Yes, it implements Unmodifiable, but that is a Collections4 class and means nothing to the compiler. It is only at run-time that the the classes throw an error for update operations. > > Regards > -- > Łukasz > + 48 606 323 122 http://www.lenart.org.pl/ > > --------------------------------------------------------------------- > To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org > For additional commands, e-mail: dev-h...@commons.apache.org > --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
