-----------------------------------
Summary: Processor for .pollEnrich incorrectly handles provided
AggregationStrategy
Key: CAMEL-8955
URL: https://issues.apache.org/jira/browse/CAMEL-8955
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.14.3
Reporter: Andy Fedotov
Priority: Minor
As it can be concluded from AggregationStrategy javadoc, and also from
available implementations such as GroupedExchangeAggregationStrategy, it should
be used in the following manner:
{code:java}
AggregationStrategy strategy = new GroupedExchangeAggregationStrategy();
Exchange result = null;
result = strategy.aggregate(result, exchange1);
result = strategy.aggregate(result, exchange2);
// ... and so on
return result;
{code}
But PollEnricher do it in following manner:
{code:java}
AggregationStrategy strategy = new GroupedExchangeAggregationStrategy();
Exchange result = strategy.aggregate(exchange1, exchange2);
return result;
{code}
This leads to incorrect result returned after aggregation and lost exchanges.
Also PollEnricher doesn't handle CompletionAwareAggregationStrategy and does
not call onCompletion(). Consequently GroupedExchangeAggregationStrategy does
not return aggregated result in the Exchange body.
