             Summary: Reprocessing fails on custom listeners
                 Key: JAMES-4212
                 URL: https://issues.apache.org/jira/browse/JAMES-4212
             Project: James Server
          Issue Type: Improvement
          Components: mailbox
            Reporter: Benoit Tellier


A customer have failed processing in dead letter for a custom listener

Reprocessing it fails with ClassNotFoundError: the group name is in the extension and not on the classpath which is not accessible as reprocessing time

I propose to switch instead of a class to a string based representation of the group name (defaulting to class name!) which would ensure that we do not have such deserialization issues.
