找不到命名查询：UnescalatedStartDeadlines在简单的工作流程上

问题描述

我是JBPM的老手，但是在JBPM 7.41中编写代码时却遇到了

pub struct CustomBin {
    eos_guard: Mutex<Option<Sender<()>>>,}

impl Default for CustomBin {
    fn default() -> Self {
        Self {
            eos_guard: Mutex::new(None),}
    }
}

impl ObjectImpl for CustomBin {
    glib_object_impl!();
}

impl ElementImpl for CustomBin {}

impl BinImpl for CustomBin {
    fn handle_message(&self,bin: &Bin,message: Message) {
        if let MessageView::Eos(_) = message.view() {
            if let Some(sender) = self.eos_guard.lock().unwrap().take() {
                sender.send(()).unwrap_or(());
            } else {
                self.parent_handle_message(bin,message);
            }
        } else {
            self.parent_handle_message(bin,message);
        }
    }
}

impl ObjectSubclass for CustomBin {
    const NAME: &'static str = "GstCustomBin";
    type ParentType = Bin;
    type Instance = ElementInstanceStruct<Self>;
    type Class = Classstruct<Self>;

    glib_object_subclass!();

    fn new() -> Self {
        Self::default()
    }
}

impl CustomBin {
    pub fn install_eos_guard(&self) -> Receiver<()> {
        let mut eos_guard = self.eos_guard.lock().unwrap();
        let (sender,receiver) = channel();

        if eos_guard.is_some() {
            panic!("End-of-stream guard was already installed");
        } else {
            eos_guard.replace(sender);
        }

        receiver
    }
}

一个简单的过程-仅记录在起始节点和结束节点之间已到达的脚本-用Java编码并在Wildfly下运行。我读到这是来自persistence.xml和几个ORM文件的问题，但我没有使用人工任务，自定义工作项处理程序等。在BusinessCentral.war或KieServer中也找不到任何ORM文件。战争。对于这个简单的示例，我是否需要Taskorm.xml和jbpmorm.xml？我已经读过这些文件放在jbpm-human-task-jpa.jar中，但是当我爆炸任何一场战争时，我都找不到那个JAR。有人可以显示我是否需要修改这些xml文件？提前谢谢！

这是我的persistence.xml
