/**
* Special exception that can be used to throw a BPMN Error from {@link JavaDelegate}s and expressions.
*
* This should only be used for business faults, which shall be handled by a Boundary Error Event or Error Event Sub-Process modeled in the process definition. Technical errors should be represented
* by other exception types.
*
* This class represents an actual instance of a BPMN Error, whereas {@link Error} represents an Error definition.
