> 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)

> org.apache.qpid.client.message.AMQMessageDelegate_0_10.getStringProperty(AMQMessageDelegate_0_10.java:735)

> 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.
