Class SpringJobExecutor

  org.camunda.bpm.engine.impl.jobexecutor.JobExecutor
      org.camunda.bpm.engine.spring.components.jobexecutor.SpringJobExecutor

public class SpringJobExecutor
extends JobExecutor

This is a spring based implementation of the JobExecutor using spring abstraction TaskExecutor for performing background task execution.

The idea behind this implementation is to externalize the configuration of the task executor, so it can leverage to Application servers controller thread pools, for example using the commonj API. The use of unmanaged thread in application servers is discouraged by the Java EE spec.
