Where are you seeing this?  How can a constructor 'return' null?

<http://docs.oracle.com/javase/7/docs/api/java/net/Socket.html>

In another post, you also said (about InetAddress.getByName()):

Again, I don't see where this is said.

<http://docs.oracle.com/javase/7/docs/api/java/net/InetAddress.html#getByName%28java.lang.String%29>

Am I looking at the wrong docs?
