InetAddress.getAllByName is broken

InetAddress.getAllByName is broken. I get the following error
when I call it:

Java.lang.ClassCastException java.net.InetAddress
        at java.net.InetAddress.getAllByName(InetAddress.java)
        at java_net_InetAddress_methods.main(java_net_InetAddress_methods.java:13)

Test Case:
class java_net_InetAddress_methods {
        public static void main (String args[]) {

                InetAddress y1 = InetAddress.getByName("tachyon");
                InetAddress y2 = InetAddress.getByName("makeda");
                InetAddress y3 = InetAddress.getByName("tachyon");
                InetAddress y4[] = InetAddress.getAllByName("tachyon");
                Properties p = new Properties();
                p.put("MYVAR","VAL");
                System.setProperties(p);


                System.out.print("y1.equals(y2) " + y1.equals(y2) + " \\n");
                System.out.print("y1.equals(y3) " + y1.equals(y3) + " \\n");

                System.out.print("y1.getAddress() " + y1.getAddress() + " \\n");


// System.out.print("y1.getAllByName(java.sun.com) " + y4[0].toString
() + " \\n");
 

                System.out.print("y1.getHostName() " + y1.getHostName() + " \\n");

                System.out.print("y1.getLocalHost() " + y1.getLocalHost() + " \\n")
;

                System.out.print("y1.hashCode() " + y1.hashCode() + " \\n");

                System.out.print("y1.toString() " + y1.toString() + " \\n");

        }
}
