>
> All calls to InetAddress.getLocalHost(*) should be replaced with this code in order to avoid a rather annoying issue with OSX 10.7 and (at least) java version "1.6.0_26":
> {code}InetAddress addr;
> try {
>    addr = InetAddress.getLocalHost();
>    System.out.println("With localhost access: " + addr);
> } catch (ArrayIndexOutOfBoundsException e) {
>    addr = InetAddress.getByName(null);
>    System.out.println("With reverse lookup: " + addr);
> }{code}
> The exception is:
> {code}Caused by: java.lang.ArrayIndexOutOfBoundsException: 0
>     at java.net.InetAddress.getLocalHost(InetAddress.java:1356){code}
