Description

If the property is missing the following code will generate an exception:
Message msg = consumer.receive();
System.out.println ("Received message ["+msg.getIntProperty("sequence")+"] sent to "+msg.getJMSDestination()); //This works

Exception in thread "main" java.lang.NumberFormatException: null
at java.lang.Integer.parseInt(Unknown Source)
at java.lang.Byte.parseByte(Unknown Source)
at java.lang.Byte.valueOf(Unknown Source)
at java.lang.Byte.valueOf(Unknown Source)

at VerySimpleReceive.receiveLoop(VerySimpleReceive.java:94)
at VerySimpleReceive.main(VerySimpleReceive.java:71)

If the same getIntProperty() is called in a MessageListener's onMessage() method then the exception is not reported and the application continues. I would expect at the very least that the error would be logged to standard error.
