Claus Ibsen resolved CAMEL-8740.
--------------------------------
Resolution: Fixed
We have a before event now
> DeadLetterChannel - Add SPI so custom components can prepare message for DLC
> ----------------------------------------------------------------------------
>
> Key: CAMEL-8740
> URL: https://issues.apache.org/jira/browse/CAMEL-8740
> Project: Camel
> Issue Type: New Feature
> Components: camel-core
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Fix For: 2.16.0
>
>
> When you use Camel's DLC as error queue, then when a message is moved to the
> DLQ, you may want to do some custom adjustment to the message before that
> happens.
> As an end user you have the onPrepare where you can do that.
> But for various Camel components then they may want to be able to hook in and
> be able to do some work.
> For example you may may want to configure camel-jms or activemq-camel to
> store the caused exception message and stacktrace as JMS headers so they are
> avalable on the JMS queue. Also for ActiveMQ we want to allow it to store the
> original destination property so AMQ broker knows which original JMS message
> the message was consumed from. This makes redelivery from the web console or
> JMX easier, as its a click on a button.
