Explanation:

Logs would look like:

INFO 2021-06-09 19:14:56,039 [[MuleRuntime].uber.06: [validationtest].batch-job-validationtestBatch_Job-work-manager @6de10f3e] [processor:

validationtestFlow/processors/1/route/0/route/0/aggregator/processors/0; event: bfb751e1-9939-11eb-9f69-02053763653a]

org.mule.runtime.core.internal.processor.LoggerMessageProcessor:

[

“”A””,

“”C””,

“”D””

]

org.mule.runtime.core.internal.processor.LoggerMessageProcessor: [

“”E””

]

Batch aggregator value is 3. Hence in first time it will print [“A”, “C”, “D”] and in next

iteration it will print [ “E” ]

Correct answer is [ “E” ]
