We have a route from a REST endpoint into a JMS (InOnly) endpoint.
We took down the broker to see what would happen. Turns out HTTP clients
hang waiting for a response (for several minutes) while a load of stack
traces are logged by Camel:

We have plugged on some onException clauses but none appear to execute:
onException(javax.jms.JMSException.class, Exception.class,
RuntimeException.class)
.log(LoggingLevel.ERROR, logger, "Exception!")
.handled(true)
.setHeader(Exchange.HTTP_RESPONSE_CODE, constant(500))
.setBody().constant("Something bad happened");
Can someone advice on what I'm missing? What we want is to respond with a
500 HTTP code but catching JMSException appears not be working.
Thanks,
James
