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

    Affects Version/s: 2.9.2
        Fix Version/s: 2.11

                       2.9.3

The empty message should have batch details so the EIPs can work with the message.

> Aggregator supports completion based on the batch consumer data (option completionFromBatchConsumer)
> Some batch consumers (eg. File) can send an empty message if there is no input (option sendEmptyMessageWhenIdle for File consumer).
> Aggregator is unable to handle such messages properly - the messages are aggregated, but Aggregator never completes.
> Here is the relevant fragment from AggregateProcessor.isCompleted(String,
> Exchange)
> int size = exchange.getProperty(Exchange.BATCH_SIZE, 0, Integer.class);
> if (size > 0 && batchConsumerCounter.intValue() >= size) {
>     ....
> }
> Please add support for this combination of options.
