> 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.
