/**
 * 
 * An incident handler that logs incidents of a certain type
 * as instances of {@link Incident} to the engine database.
 *
 * 
 * By default, the process engine has two default handlers:
 * 
 * type failedJob: Indicates jobs without retries left. This incident handler is active by default and must be disabled
 * via {@link org.camunda.bpm.engine.ProcessEngineConfiguration#setCreateIncidentOnFailedJobEnabled(boolean)}.
 * type failedExternalTask: Indicates external tasks without retries left
