---------------------------------
Resolution: Fixed
> UseOriginalAggregationStrategy doesn't set EXCEPTION_CAUGHT property on
> exception propagation
> ---------------------------------------------------------------------------------------------
>
> Key: CAMEL-20844
> URL: https://issues.apache.org/jira/browse/CAMEL-20844
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 4.4.0
> Reporter: Eduard Gomoliako
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.8.0
>
>
> I have the following problem: {{onCompletion}} processor on a route can’t
> find a caught exception in Exchange that occurred inside {{Split}} with
> {{UseOriginalAggregationStrategy}} aggregation strategy.
>
> Long story short:
> * {{Split}} processor got only one message from the split expression
> * Sending it down to the next processor failed because of exception
> * {{RedeliveryErrorHandler}} sets {{EXCEPTION_CAUGHT}} property on the
> exchange ({{{}prepareExchangeAfterFailure{}}} method)
> * On Aggregation: {color:#000000}{{UseOriginalAggregationStrategy}}
> {{aggregate}} method took the exception and set it to the original exchange
> (didn’t copy the {color}{{EXCEPTION_CAUGHT}} property though)
> * The {color:#000000}{{OnCompletionProcessor}} in the {{doProcess}} method
> clears the exception sending it down to the {{onCompletion}} processors{color}
> * {color:#000000}Exchange in the {{onCompletion}} processor doesn’t have an
> exception and has no {color}{{EXCEPTION_CAUGHT}} property.
>
> {color:#000000}Is this an expected behavior?{color}
> {color:#000000}Should the {color}{{UseOriginalAggregationStrategy}} copy the
> {{EXCEPTION_CAUGHT}} property as well?
> Or probably it would be better if {color:#000000}{{OnCompletionProcessor}}
> sets it in case of clearing the exception, wouldn’t it?{color}
> {color:#000000} {color}
> {color:#000000}Thank you in advance for sharing your thoughts.{color}
