> If any exception happens when ConsumerJMS tries to read messages, the process tries again immediately.
> {code:java}
> try {
> consumer.consume(destinationName, errorQueueName, durable, shared, subscriptionName, charset, new ConsumerCallback() {
> @Override
> public void accept(final JMSResponse response) {
> if (response == null) {
> return;
> }
> FlowFile flowFile = processSession.create();
> flowFile = processSession.write(flowFile, out -> out.write(response.getMessageBody()));
> final Map<String, String> jmsHeaders = response.getMessageHeaders();
> final Map<String, String> jmsProperties = response.getMessageProperties();
> flowFile = ConsumeJMS.this.updateFlowFileAttributesWithJMSAttributes(jmsHeaders, flowFile, processSession);
> flowFile = ConsumeJMS.this.updateFlowFileAttributesWithJMSAttributes(jmsProperties, flowFile, processSession);
> flowFile = processSession.putAttribute(flowFile, JMS_SOURCE_DESTINATION_NAME, destinationName);
> processSession.getProvenanceReporter().receive(flowFile, destinationName);
> processSession.putAttribute(flowFile, JMS_MESSAGETYPE, response.getMessageType());
> processSession.transfer(flowFile, REL_SUCCESS);
> processSession.commit();
> }
> });
> } catch(Exception e) {
> consumer.setValid(false);
> throw e; // for backward compatibility with exception handling in flows
> }
> }
> {code}
> It should call {{context.yield}} in exception block. Notice [PublishJMS|https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-jms-bundle/nifi-jms-processors/src/main/java/org/apache/nifi/jms/processors/PublishJMS.java#L166] is yielded in the same scenario. It is requires to do in the ConsumeJMS processor only.
