Why are you checking listString.isEmpty() to set it empty after? Am I
missing something?

> Key: NIFI-2724
> URL: https://issues.apache.org/jira/browse/NIFI-2724
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Extensions
> Affects Versions: 1.0.0
> Environment: All platforms with Java RMI support for JMX
> Reporter: Brian Burnett
> Assignee: Andre F de Miranda
> Priority: Minor
> Labels: processor
> Attachments: 0001-NIFI-2724-New-JMX-Processor.patch
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> The JMX Processor feature addition includes only GetJMX without
> SecurityManager capabilities at this time. The processor in its current
> state is capable of pulling MBean Property and Attribute values from a remote
> RMI Server. Each set of Mbean data is wrapped in a JSON formatted FlowFile
> for downstream processing. It has the ability to control content with
> whitelist and blacklist properties.
> Possible use for this processor and the reason it was created is to help make
> sense of Kafka server metrics.
> Will followup with a SecurityManager Context Service and PutJMX Processor.
