java.net.InetAddress.getLocalHost().getHostName() is returning localhost instead of the server's hostname in the Java 8

Solution Verified - Updated -

Issue

During the process of migration from JBOSS 6.4 to 7.2, it was verified that when calling java.net.InetAddress.getLocalHost().getHostName(), it is getting localhost back instead of the FQDN of the server. If it is set -Djava.net.preferIPv4Stack=false, it returns the FQDN, but IPv6 addresses are not used, only IPv4. Is there another option to function call returns the FQDN instead of localhost?
