The wait loop in helloworldtopicnotifier/ReceiveJMSMessage.java consists of: 

while (true) { } 

Which ties up the CPU. The other quickstarts ReceiveJMSMessage.java classes use a timeout/sleep to avoid this - Such as (from the notification, aggregator, others - quickstarts):

        while (true) { // loop until I'm killed
            try {
                Thread.sleep(500);
            } catch (InterruptedException e) {break;}
        }
