InetAddress java 8 is not getting the hostname

InetAddress.getLocalHost().getHostName() is no more getting the name of the HostName since I switched to java 8 ...

with the jdk1.8 the InetAddress.getLocalHost().getHostName() returns "localhost". Before (when I was using jdk1.6) it gives me the right hostname (which is "ACTION03") according to the network config :

cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=ACTION03

any help ?

Works for me on Linux (Ubuntu 14.04) with Java 1.8.0_05.

public class HostName {
    public static void main(String[] args) throws Exception {
        System.out.println(java.net.InetAddress.getLocalHost().getHostName());
    }
}
