NIFI-4726: Avoid concurrency issues in JoltTransformJSON
----
> Concurrency issue with JoltTransformJson
> ----------------------------------------
>
> Key: NIFI-4726
> URL: https://issues.apache.org/jira/browse/NIFI-4726
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Marco Gaido
>
> JoltTransformJson uses under the hood Jackson to parse JSONs. On heavy
> multithreading workloads, Jackson can have concurrency problem, as also
> described in this Stackoverflow thread
> https://stackoverflow.com/questions/17924865/jsonmappingexception-was-java-lang-arrayindexoutofboundsexception.
> This can cause all the parsing to fail when this problem occurs.
