> -----------------------------------------------------------------------------------
>
> Key: QPID-2959
> URL: https://issues.apache.org/jira/browse/QPID-2959
> Project: Qpid
> Issue Type: Bug
> Components: Java Client
> Affects Versions: 0.8
> Reporter: Rajith Attapattu
> Assignee: Rajith Attapattu
> Priority: Minor
> Fix For: 0.9
>
>
> If the ReplyTo exchange is not set on a message read by the Java client, and
> getJMSReplyTo is called, the code does not properly handle the exchange being
> null.
> In the following code, replyTo.getExchange() returns null, so the String
> exchange is set to null, and thus the first argument to generateDestination
> ends up being null.
> AMQMessageDelegate_0_10.getJMSReplyTo() line: 224
> if (dest == null)
> {
> String exchange = replyTo.getExchange();
> String routingKey = replyTo.getRoutingKey();
> dest = generateDestination(exchange == null ? null : new
> AMQShortString(exchange),
> routingKey == null ? null : new
> AMQShortString(routingKey));
> In the following code, you can see that if the first argument (exchange) is
> null, you'll get a null pointer exception when the code attempts to call
> exchange.asString().
> protected AMQDestination generateDestination(AMQShortString exchange,
> AMQShortString routingKey)
> {
> AMQDestination dest;
> ExchangeInfo exchangeInfo = _exchangeMap.get(exchange.asString());
