SubOpts bits not getting set

[joelcdunn]

Synopsis: Setting the BITs NoLocal and the other SubOpts parameters using the Java Client, however we are not seeing them set when the SUBSCRIBE gets to the Server, only the QoS of SubOpts makes the trip.

Test Case sets QoS:2 and NoLocal in the Subscription Options for topic

Code Snippet:
case PAHOV5:
org.eclipse.paho.mqttv5.common.MqttSubscription [] subs =
new org.eclipse.paho.mqttv5.common.MqttSubscription[1];
subs[0] = new org.eclipse.paho.mqttv5.common.MqttSubscription(topic, subopt&3);
System.out.println("MqttSubscription: " + subs[0]);
if ((subopt&4) != 0){
subs[0].setNoLocal(true);
System.out.println("setting noLocal true");
}
if ((subopt&8) != 0){
subs[0].setRetainAsPublished(true);
System.out.println("setting retainAsPublished true");
}
if ((subopt&0x30) != 0){
subs[0].setRetainHandling((subopt&0x30)>>4);
System.out.println("setting retainHandling");
}
System.out.println("MqttSubscription: " + subs[0]);

        MqttProperties mprops2 = new MqttProperties();
        if (subid != null ) {
            mprops2.setSubscriptionIdentifier(subid);
        }
        
        org.eclipse.paho.mqttv5.client.IMqttToken subToken = null;
        try {    
            subToken = pahoConnv5.subscribe(subs, null, null, mprops2);
            subToken.waitForCompletion();
            grantedQoS = subToken.getReasonCodes();
        }
