Reactive find with lock in Quarkus with reactive hibernate

[alexjaravete]

Hi, when using Quarkus with reactive hibernate and trying to run this findById(id, LockModeType.PESSIMISTIC_WRITE), I get following Error: JPA error: java.lang.UnsupportedOperationException

The error seems to be coming from here:

hibernate-reactive/hibernate-reactive-core/src/main/java/org/hibernate/reactive/event/impl/DefaultReactiveLockEventListener.java

Lines 238 to 241 in 5cb015d

	@Override
	public void onLock(LockEvent event) throws HibernateException {
	throw new UnsupportedOperationException();
	}

Is this intended, or is the implementation not finished? I can see that the last time this was edited was 4 years ago.

It seems like a bug. We shouldn't call this method. We should call .reactiveOnLock.

I've tried to change one of the quarkus quickstarts to see the error, but I couldn't recreate it.
Could you provide a reproducer, please?
Or, at least, you could tell what's different from your use case.

I tried your quickstart example and the error does not show up.
The difference is that we are using Kotlin.
But even after rewriting everything to Kotlin, the error still does not show up.
Now I am trying to find out what the difference between our set-up and the quickstart project is.

I will let you know if I can reproduce it in the quickstart project.

Thanks.

I'm going to close this issue for now. Feel free to reopen it or comment here when you have a test case.
