Again, according to [Travis](https://travis-ci.org/ReadyTalk/avian/builds/13552347) this method is required by a couple of places (and it is [part of the official Java API](http://docs.oracle.com/javase/7/docs/api/java/net/InetSocketAddress.html#getHostName%28%29), too).

How about replacing the function body with:

```java
return address.getHostAddress();
```

for now?
