Re: Returns 127.0.0.1 at HostInterceptor

Sorry  to jump on this thread so late but you should be aware that getLocalHost() seems to have a nasty habit of throwing a HostNotFoundException on Java 7.  I ran into this in Log4j 2 and had to write some code to deal with that when it happens.  See http://blog.leon-rosenberg.net/2012/08/oracle-kills-getlocalhost-on-macos-x-in.html
