quarkus 事务失效

Question

pom 文件如下

 <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-narayana-jta</artifactId>
    </dependency>
    <dependency>

      <artifactId>quarkus-mongodb-client</artifactId>

    <dependency>
      <groupId>org.projectlombok</groupId>
      <artifactId>lombok</artifactId>
      <version>1.18.22</version>
    </dependency>

代码如下

 public  String  testAffairTemp(String name) throws Exception{

            Student studentByName = new Student().getStudentByName(name);
        try{
            transaction.begin();
            studentByName.setName("年糕");
            studentByName.persistOrUpdate();
            studentByName.update();
            Student student = new Student();
            student.setName("美猴王");
            student.setAge(27);
            student.setPhone("123123123");
            student.setId(new ObjectId("62779c8c364eef2a0479f57b"));
            student.persist();
            transaction.commit();
        }
        catch (RuntimeException  e){
            transaction.rollback();
            System.out.println("yunxing");
            e.printStackTrace();
        }
        catch (Exception e){
            System.out.println("抓到不会滚异常");
            e.printStackTrace();
        }

        return studentByName.toString();
    }

其中 student.setId(new ObjectId("62779c8c364eef2a0479f57b")); 这句话我故意制造runtimeexception 但是异常时抓到了但是并没有回滚
附官网代码如下：

@ApplicationScoped
public class SantaClausService {

@Inject ChildDAO childDAO
@Inject SantaClausDAO santaDAO
@Inject UserTransaction transaction

public void getAGiftFromSanta(Child child, String giftDescription) throws Exception {
    // some transaction work
    try {
        transaction.begin();
        Gift gift = childDAO.addToGiftList(child, giftDescription);
        santaDAO.addToSantaTodoList(gift);
        transaction.commit();
    }
    catch(SomeException e) {
        // do something on Tx failure
        transaction.rollback();
    }
}

}

不理解为什么事务会失效，是因为我用了uni去接纳数据的原因吧 ，有可能是uni是异步非阻塞的所以可能不是同一个事务了，求解答
