--------------------------------------------------------
Key: AMQ-689
URL: https://issues.apache.org/activemq/browse/AMQ-689
Project: ActiveMQ
Type: Bug

Reporter: Rodrigo S. de Castro
I have redelivery configured, but when it fails in all attempts (through a
RuntimeException), I get the following message:
11:00:54,775 DEBUG [ServerSessionImpl:0] Endpoint failed to process message.

The code that throws this NPE is ServerSessionImpl, whose excerpt I send below.
There are more reports of this
try {
endpoint.afterDelivery();
} catch (Throwable e) {
throw new RuntimeException("Endpoint after delivery
notification failure", e);
} finally {
if( session.getTransactionContext().isInLocalTransaction() ) {
<<<<--------------------------- NPE
if( !useRAManagedTx ) {
// Sanitiy Check: If the local transaction has not been
commited..
// Commit it now.
log.warn("Local transaction had not been commited.
Commiting now.");
}
try {
session.commit();
} catch (JMSException e) {
log.info("Commit failed:", e);
}
}
}
