>
> 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 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.
