RedeliverErrorHandler - Should make defensive copy of Exchange so redelivery
works for using Processor
------------------------------------------------------------------------------------------------------
Key: CAMEL-4117
URL: https://issues.apache.org/jira/browse/CAMEL-4117
Project: Camel
Issue Type: Improvement
Components: camel-core
Affects Versions: 2.7.0
Reporter: Claus Ibsen
Assignee: Claus Ibsen
Fix For: 2.8.0, 2.9.0
When using redelivery with the Camel error handler, it will by default use the
_previous_ exchange when redelivering. This ensures that any changes that was
done by the failed attempt does not reflect when a redelivery is performed (eg
think like use original message). However this does not apply when end users
uses the low level .process in their Camel routes. So if they change the
Exchange in the .process and then some error occurs, then that change is
redelivered.
We should consider making the redelivery error handler do a defensive copy of
the exchange, so it can redelivery without any changes/side effects. For
example this happens when people use .bean or any of the other EIPs. So why not
for .process as well?
