java.lang.NumberFormatException silently ignored in
MessageListener.onMessage(Message message)
----------------------------------------------------------------------------------------------
Key: QPID-906
URL: https://issues.apache.org/jira/browse/QPID-906
Project: Qpid
Issue Type: Bug
Components: Java Client
Affects Versions: M2.1
Environment: JDK 1.6
Reporter: Alasdair MacLeod
Priority: Minor
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.
