----------------------------------
Summary: Include message history in stacktraces from error
handler, making it easier to know where the problem was
Key: CAMEL-6407
URL: https://issues.apache.org/jira/browse/CAMEL-6407
Project: Camel
Issue Type: New Feature
Components: camel-core, eip
Reporter: Claus Ibsen
Assignee: Claus Ibsen
Fix For: 2.12.0
See post on dev mailing list
http://camel.465427.n5.nabble.com/HEADS-UP-Camel-routing-engine-dumps-message-history-when-exhausted-exception-is-logged-tp5733516.html
This allows us to dump stacktraces with details about how the message has been
routed, (aka using the message history eip).
An example could be
