> NiFi is unable to populate over 1/4 of AMQP properties from flow properties
> ---------------------------------------------------------------------------
>
> Key: NIFI-1686
> URL: https://issues.apache.org/jira/browse/NIFI-1686
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 0.5.1
> Reporter: Stephen Harper
>
> When creating a flow (we used ListenHTTP, but this bug will affect all) that
> forwards on to a rabbit queue, org.apache.nifi.amqp.processors.PublishAMQP
> uses the method extractAmqpPropertiesFromFlowFile to populate the AMQP
> BasicProperties if the flow attributes match a certain format (i.e
> amqp$contentType=text/xml).
> The method in question uses reflection to find a matching method name from
> the AMQP.BasicProperties class, and tries to populate accordingly.
> This works fine for all properties that take a String argument - however
> there are some that don't (specifically, headers takes a Map<String, Object>,
> deliveryMode and priority take Integer, and timestamp takes a Date), and it
> is impossible to populate these values because the invocation assumes a
> String is required, and fails on line 210.
> Whatsmore, the comment underneath (line 215) states that "this should really
> never happen since it should be caught by the above IF" - however the author
> of the code mustn't have tested all cases because this error is consistently
> present when trying to forward flow attributes in over a quarter of the
> available amqp properties.
