----------------------------------------
Hi,
for parallel processing there is a new option: stopOnAggregateException().
This was introduced in #CAMEL-10272
[https://github.com/apache/camel/commit/43036a4a574873feaa421abbb5393f865714d790]
I think this can be closed

> Key: CAMEL-12318
> URL: https://issues.apache.org/jira/browse/CAMEL-12318
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.16.5, 2.20.2
> Environment: Java 8
> Reporter: Xilai Dai
> Priority: Major
>
> In case of any exception thrown from aggregate() of the custom
> AggregationStrategy class, the exception is hiden by Camel core and couldn't
> be catched by any errorhandler.
> A simple use case project is created for easy reproduce this issue,
> https://github.com/xldai/test/tree/master/test-multicast
> With setting camel.ver to 2.15.x in the pom.xml, the Exception is thrown as
> expected:
> {code:java}
> Caused by: java.lang.RuntimeException: Deliberate Exception
> at
> beans.FD_MulticastAggregator.aggregate(FD_MulticastAggregator.java:16)
> at
> org.apache.camel.processor.MulticastProcessor.doAggregateInternal(MulticastProcessor.java:848)
> at
> org.apache.camel.processor.MulticastProcessor.doAggregate(MulticastProcessor.java:830)

> org.apache.camel.processor.MulticastProcessor$AggregateOnTheFlyTask.aggregateOnTheFly(MulticastProcessor.java:489)
> at
> org.apache.camel.processor.MulticastProcessor$AggregateOnTheFlyTask.run(MulticastProcessor.java:394){code}
> With setting camel.ver to higher than 2.16.x in the pom.xml, the Exception is
> not exposed anymore.
> Looking into the commit changes, seems this is happening after the changes of
> CAMEL-8587.
