Oops, the method name is correct, but the assertion was wrong, and needs to
be fixed.
> Allow per Exception error handling in the mailet pipeline
> ---------------------------------------------------------
>
> Key: JAMES-2275
> URL: https://issues.apache.org/jira/browse/JAMES-2275
> Project: James Server
> Issue Type: New Feature
> Components: Mailet Contributions
> Affects Versions: master
> Reporter: Tellier Benoit
> Labels: easy-fix, feature, newbie
>
> In JAMES-2271 from [~apptaro], the error handling system of the mailet
> pipeline can now be customized using the *onMailetException* property. This
> allows specifying the processor for error handling or ignore the error (by
> default error processor is triggered).
> While empowering the user to write custom error handling logic, the error
> handling code capabilities is limited as the original exception is lost along
> the way.
> We should:
> - Pass the Exception along with the Mail, as an attribute.
> Thus mailet in the error processor can access and read it. Throwable being
> serializable, this makes this change easy to perform.
> - Implement specific error handling matchers:
> - *HasException* would allow to see if a Mail has a specific exception
> {code:xml}
> <mailet
> match="HasException=org.apache.james.managesieve.api.ManageSieveException"
> class="...>
> ....
> </mailet>
> {code}
> ### How to implement this
> 1. Add a ERROR_ATTRIBUTE_NAME contant in the Mail interface
> 2. ProcessorUtil:: handleException should add the ERROR_ATTRIBUTE_NAME
> attriute using the provided exception
> 3. Modify *AbstractStateMailetProcessorTest* to demonstrate that when a
> mailet or a matcher throws, the Exception is attahed to the incoming mail.
> 4. In the mailet/standard project, you will implement the HasException
> matcher. You can extend GenericMatcher and implement unit tests for your
> class.
