> I have come across an issue with Camel 2.13 when subscribing to a qpid messages published by a non-camel producers. The error happens with both Qpid C++ producer and also a python producer. 
> An Null pointer exception is thrown in the JmsBinding.extractHeadersFromJMS on line 173. 
> map.put("JMSXUserID", jmsMessage.getStringProperty("JMSXUserID")); 
> JMSXUserID has not been set by the publisher as it is a non-JMS publisher. 
> java.lang.NullPointerException
> at java.lang.String.<init>(String.java:593)
> at org.apache.qpid.client.message.AMQMessageDelegate_0_10.getStringProperty(AMQMessageDelegate_0_10.java:735)
> at org.apache.qpid.client.message.AbstractJMSMessage.getStringProperty(AbstractJMSMessage.java.225)
> at org.apache.camel.component.jms.JmsBinding.extractHeadersFromJms(JmsBinding.java:173)
> at org.apache.camel.component.jms.JmsMessage.populateInitialHeaders(JmsMessage.java:222)
> Full stack trace not show as it is on a different system
> I can see a change was made to JmsBinding.java in Camel 2.12.2 to fix a ActiveMQ issue. This is what has caused the issue. The system is being upgraded from Camel 2.9.2 to Camel 2.13.1 and this issue has been experienced.
