We are using iPOJO 1.6.2 and I have a method as follows. Is this a valid
combination of options as I am getting a null value passed to it when a
ClockSubscriber is added. (At startup they were added fine, but when I
remove&add back a component it is always null)
@Requires)optional = true, id = "subscribers")
private ClockSubscriber[] subscribers;
@Bind(aggregate = true, id = "subscribers", optional = true)
public void subscriberBound(ClockSubscriber subscriber) {
try {
if(subscriber == null) throw new NullPointerException();
And this exception
java.lang.NullPointerException
