Is Thread.sleep() really required?

>                 URL: https://issues.apache.org/jira/browse/FALCON-226
>             Project: Falcon
>          Issue Type: Bug
>          Components: common, messaging, rerun
>    Affects Versions: 0.3
>            Reporter: Shaik Idris Ali
>            Assignee: Shaik Idris Ali
>              Labels: test
>             Fix For: 0.5
>         Attachments: FALCON-226.patch
>   Original Estimate: 24h
>  Remaining Estimate: 24h
> Post-processing step of parent workflow uses Falcon system JMS topic to send messages,
which are used for retrying failed instances and handling late rerun.
> Before migration, IVORY.ENTITY.TOPIC is used for sending the messages, which is hard-coded
in post-processing classes, post migration new processes send messages to FALCON.ENTITY.TOPIC.
> However, the subscriber to listen to this topic is configurable in startup.properties
> *.entity.topic=FALCON.ENTITY.TOPIC
> So, after migration, admin needs to configure the topic to listen to both old and new
ENTITY.TOPIC, since activemq supports multiple topic subscription so a comma separated topic
list should be configured.
> More test-cases needs to be added to FalconTopicProducer and FalconSubscriberService.
