I work on a Windows system and hence can't test/reproduce anything related to this. Based on what i have seen the posts (that i referred in my earlier reply), JBoss expects the hostname entry to be present/mapped in the /etc/hosts file. So the simplest way to get this working is, every time your hostname changes, you will have to edit the /etc/hosts file to map the IP and the hostname.
