Claus Ibsen commented on CAMEL-860:
-----------------------------------
Dario it is working as exepected. I have added some more unit test to verify
that the original caused exception is on the exchange.
However I can see what your problem is. You DLC is a *jms* queue. And the JMS
spec doesn't allow to send complex objects as properties on a JMSMessage. So
the exception object is lost when its send to the JMS queue, only the body and
simple properties is sent.
The issue is that we need the JMS producer to send the entire exchange as an
object to the JMS queue.
I will create a ticket for this feature in JIRA.

> Key: CAMEL-860

> Project: Apache Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 1.4.0
> Environment: Windows XP, JDK 6
> Reporter: dario sanna

> Fix For: 1.5.0

> Original Estimate: 5 minutes

> The DeadLetterChannel does not set the EXCEPTION_CAUSE_PROPERTY.
> It looks like a bug in the method:
> public boolean process(final Exchange exchange, final AsyncCallback callback,
> final RedeliveryData data)
> The property is set by getting the Exception from the exchange:
> exchange.setProperty(EXCEPTION_CAUSE_PROPERTY, exchange.getException());
> but several lines before the Exception ist set to null in exchange:
> if (exchange.getException() != null) {
> Throwable e = exchange.getException();
> exchange.setException(null); // Reset it since we are
> handling it.
> to fix the bug, i think it is simply done by preserving the Throwable like
> this
> Throwable e = exchange.getException();
> if (exchange.getException() != null) {
> exchange.setException(null); // Reset it since we are
> handling it.
> ...
> exchange.setProperty(EXCEPTION_CAUSE_PROPERTY, e);
