Hello.

We are using Hibernate inside WildFly (v10) JEE container.

We use @EntityListeners where we fire a CDI event inside a method annotated with @PreUpdate.

These are the CDI observer methods listening to the events fired in the EntityListener:
Code:
@Asynchronous
public void onSuccess(@Observes(during = TransactionPhase.AFTER_SUCCESS) MyData event) {

@Asynchronous
public void onFailure(@Observes(during = TransactionPhase.AFTER_FAILURE) MyData event) {

What is strange here, is that always the onFailure() method is called although the data is written to the db and no exceptions or any errors can be seen - meaning the transaction has been comitted.
We also use RootAware[1] for the children entities. Don't know, if this matters.

Would be great, if anyone could explain, why this is not working as expected!

Thanks,
Michael

Try adding a call to Thread.dumpStack(), to show the call stack of what called your onFailure(). That should give you an idea of why it is being called. I haven't heard of others hitting this, so not sure why your seeing it.

We also released WildFly 11, so you could try recreating with that (to see if your problem has been fixed), if the above doesn't help.
