Claus Ibsen commented on CAMEL-1689:
------------------------------------
JMSDestination is *not* possible to set in a IN header as it can cause jms
routing to go into looping such as:
{code}
from("jms:queue:foo").to("jms:queue:bar")
{code}
In this case when we receive a message from *foo* then it will populate a Camel
message that contains the details from the javax.jms.Message and thus also
{{JMSDestination}}.
And it will be {{queue://foo}}. So when the message is routed to the {{to}}
endpoint then it will mistakenly send it back to itself, instead of using the
{{queue:bar}} destination defined on the endpoint.

> Key: CAMEL-1689
> URL: https://issues.apache.org/activemq/browse/CAMEL-1689
> Project: Apache Camel
> Issue Type: Bug
> Components: camel-jms
> Affects Versions: 2.0-M1
> Reporter: Siegfried Wirth
> Assignee: Claus Ibsen
> Fix For: 2.0.0
>
>
> Camel jms producer ignores some JMSHeaders. For example the header
> JMSPriority is ignored - due to the comment in the code, because it is set by
> the producer. But it should not only be set by the produer due to the
> received message, it should also be possible to set a priority using the
> JMSPriority header on the consumer. (See also the option preserveMessageQos
> on the jms endpoint - if every JMSHeader is ignored by the producer it is
> impossible to set Qos-Properties on the message.)
> The reason for the bug is in
> org.apache.camel.component.jms.JmsBinding#appendJmsProperty.
> The follwoing JMS message headers are useful for sending messages and
> therefore should be copied to the jms message:
> - JMSDestination
> - JMSDeliveryMode
> - JMSExpiration
> - JMSPriority
> - JMSMessageID
> - JMSTimestamp
