>
> EvaluateJsonPath does a lot of work in every onTrigger() that can be done
> when scheduled. This has the effect of making it take more cpu cycles than
> necessary to do its job.
> Initializing the -JsonPath objects in a ThreadLocal- recycling JsonPath
> objects from a queue and getting the properties from the ProcessContext a
> single time in onSchedule() should reduce the amount of CPU time this
> processor needs to perform a given task.
