Marnie McCormack updated QPID-906:
----------------------------------
Fix Version/s: (was: M4)
> 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
> org.apache.qpid.client.message.JMSHeaderAdapter.getByte(JMSHeaderAdapter.java:171)
> at
> org.apache.qpid.client.message.JMSHeaderAdapter.getShort(JMSHeaderAdapter.java:185)
> at
> org.apache.qpid.client.message.JMSHeaderAdapter.getInteger(JMSHeaderAdapter.java:198)
> at
> org.apache.qpid.client.message.AbstractJMSMessage.getIntProperty(AbstractJMSMessage.java:361)
> 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.
