I created a test project here:
github.com/sfeliks/retry-test
When application is executed and Scheduler starts, SchedulerService throws test RuntimeException. It is expected application tries 3 times and and finishes. The actual result is that even when exception would not be thrown on any of retries, processing still would fail. In current state, job finishes with two errors:

我认为这个问题是这个的重复：https://stackoverflow.com/questions/76043558/quarkus-mutiny-retry-failes-because-on-another-thread?noredirect=1#comment134500410_76043558
问题是由.withBackoff引起的。
当使用 Hibernate Reactive 时，会检查会话的两个事项：
- 会话必须在事件循环线程中调用。
- 会话必须在创建它的同一线程中使用。
在这种情况下，第一个检查由于 Mutiny 中的一个限制（或错误）而失败：在使用.withBackoff选项进行重试时，uni 运行在工作线程中（而不是事件循环线程中创建会话的线程）。
请注意，即使创建新会话，由于代码不是在工作线程（而是事件循环线程）中运行，检查也会失败。
这在 Quarkus 2.16 中有效，因为有一个检查确保所有内容都在事件循环线程中运行。但在 Quarkus 3 中删除了此检查，这可能是一个错误。
目前，我没有解决方法，但是如果避免使用.withBackoff选项，应该可以解决问题。

I think this is a duplicate of this: https://stackoverflow.com/questions/76043558/quarkus-mutiny-retry-failes-because-on-another-thread?noredirect=1#comment134500410_76043558
The problem is caused by .withBackoff.
Hibernate Reactive checks two things when the session is used:
- The session must be called in a event-loop thread
- The session must be used in the same thread it has been created.
In this case, the first check is failing because of a limitation (or bug) in Mutiny: when retrying using the .withBackoff option, the uni runs in a worker thread (and not in the event-loop thread the session was created).
Note that even if you create a new session, the check will fail because the code it's not running in a worker-thread (and not a event-loop thread).
This works with Quarkus 2.16 because there is a check that makes sure that everything runs in an event-loop thread. This check has been removed in Quarkus 3, this is probably a bug.
At the moment, I don't have a workaround, but it should work if you avoid the .withBackoff option.
