Hi,

As requested, there is now a branch based on the master with the source code to run the discussed test.
The following branch comparison shows the changes.
https://github.com/wildfly/wildfly/compare/master...99sono:WFLY-8954-from-master

This branch is called:
WFLY-8954-from-master

I do not have a big time window available to me.
But I will now study the org.eclipse.persistence.transaction package of eclipselink, see the class architecture present within this package and the business process implemented by these components. 
And see where I might be bale to override functionality to what you suggest.


The following image is a basic class diagram with the core components that may have to be hacked/overriden to address this issue.

Let us see how the fishing goes.

Many thanks.

>          Issue Type: Bug
>          Components: JPA / Hibernate

> Hi,
> In widlfly there seems to be an important issue concerning CDI events and observing these events during onsuccess. At least while using eclipselink.
> When using wildfly 10.0.0.Final together with eclipselink, if an application modifies an entity A, fires an event stating entity A has been modified, and an observer consumes this event during transaction success.
> Then the observer will be working with stale entities that do not reflect the modifications done to the entity.
> A sample application for this issue is available in:
> https://github.com/99sono/wildfly10-observe-on-success-stale-entity
> The widlfly configuration xml for the sample application, is available in the application itself, as can be seen in the readme documentation.
> Many thanks for taking a look.
> Kindest regards.
