我使用spring-module工具，调用jBPM提供的方法 GraphSession.deleteProcessInstance()。按理说，既然jBPM提供了方法来删除流程实例，那么就应该把相关的东西统统都删掉才对，可是看错误信息，似乎还得调用这个方法的人来删除相关对象。

是不是我不应该调用这个方法？是不是jBPM提供了其他的删除流程实例的方法我没有找到呢？


代码如下：

	public void deleteProcessInstance(final Long processInstanceId) {
		this.jbpmTemplate.execute(new JbpmCallback() {
			@Override
			public Object doInJbpm(JbpmContext context) throws JbpmException {
				context.getGraphSession().deleteProcessInstance(processInstanceId);
				return null;
			}
		});
	}

错误信息如下：
