Xilai Dai created CAMEL-12318:
---------------------------------
Summary: Exception from aggregate() of AggregationStrategy has
been hiden since Camel 2.16.x
Key: CAMEL-12318
URL: https://issues.apache.org/jira/browse/CAMEL-12318
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.20.2, 2.16.5
Environment: Java 8
Reporter: Xilai Dai
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

beans.FD_MulticastAggregator.aggregate(FD_MulticastAggregator.java:16)

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.
