Java client null pointer exception thrown when there is no exchange set for
ReplyTo
-----------------------------------------------------------------------------------
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());
