---------------------------------------

             Summary: onCompletion not called on Splitter configured with CompletionAwareAggregationStrategy and shareUnitOfWork=true
                 Key: CAMEL-9887
                 URL: https://issues.apache.org/jira/browse/CAMEL-9887
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.17.0
            Reporter: Jerry Williamson


In 2.17.0, if a Splitter is configured with shareUnitOfWork=true, then its AggregationStrategy is now wrapped by a ShareUnitOfWorkAggregationStrategy. This causes the following code from *MulticastProcessor.doDone()* to fail to invoke onCompletion when the configured strategy implements CompletionAwareAggregationStrategy.

{noformat}
if (strategy instanceof CompletionAwareAggregationStrategy) \{
            ((CompletionAwareAggregationStrategy) strategy).onCompletion(subExchange);
\}
{noformat}

It appears the change was a part of CAMEL-9573.

I haven't completely analyzed the shared unit of work changes but one possible approach to fix this would be to have the ShareUnitOfWorkAggregationStrategy implement CompletionAwareAggregationStrategy and then have its onCompletionMethod delegate to the wrapped strategy iff it also implements CompletionAwareAggregationStrategy.
