Assignee: Keith Wall
> [Java 0-8...0-9-1 Client] Calling getJMSReplyTo on a received message can
> lead to NullPointerException
> ------------------------------------------------------------------------------------------------------
>
> Key: QPID-7898
> URL: https://issues.apache.org/jira/browse/QPID-7898
> Project: Qpid
> Issue Type: Bug
> Components: Java Client
> Reporter: Lorenz Quack
> Assignee: Keith Wall
> Fix For: qpid-java-client-0-x-6.3.0
>
>
> A call to {{Message#getJMSReplyTo()}} can lead to a {{NullPointerException}}.
> {noformat}java.lang.NullPointerException
> at
> org.apache.qpid.client.message.AMQMessageDelegate_0_8.getJMSReplyTo(AMQMessageDelegate_0_8.java:301)
> at
> org.apache.qpid.client.message.AbstractJMSMessage.getJMSReplyTo(AbstractJMSMessage.java:104){noformat}
> The circumstances are
> * a Message received over AMQP 0-8...0-9-1
> * the replyTo set to a non-BURL address not containing a slash ("/")
> * the address must not exist in the
> org.apache.qpid.client.message.AMQMessageDelegate_0_8#_destinationCache
> The code throwing the NPE:
> {code:title=AMQMessageDelegate_0_8#getJMSReplyTo (slightly edited for
> clarity)}public Destination getJMSReplyTo() throws JMSException
> {
> String replyToEncoding =
> getContentHeaderProperties().getReplyToAsString();
> Destination dest;
> try {
> BindingURL binding = new AMQBindingURL(replyToEncoding);
> // something else
> } catch (URISyntaxException e) {
> if (replyToEncoding.startsWith("/")) {
> // something
> } else if (replyToEncoding.contains("/")) {
> // something
> } else if (getAMQSession().isQueueBound(replyToEncoding, null, null))
> {
> // THE ABOVE CALL TO getAMQSession THROWS A NPE!!!
> } else {
> // something
> }
> }
> return dest;
> }{code}
> The root cause seems to be that we are relying on the Message having
> knowledge of the session but we aren't setting the Session on the Message on
> all code paths.
> I encountered this testing message conversion.
