0040046: unnecessary objects are created every time any DAL object is created/updated/deleted

DescriptionEntityPersistenceEventObserver should be declared as an @ApplicationScoped bean, otherwise when a new event (save, update, delete, transaction begin, transaction completed) is fired a new instance of every EntityPersistenceEventObserver listening to that particular event is created.
Steps To Reproduce1) Apply the provided patch, which writes in the log every time a new instance of EntityPersistenceEventObserver is created.
2) Go to the [Sales Order]
3) Create a new record. Check in the log that a new instance of every EntityPersistenceEventObserver listening to the save event is created.
4) Create another record. Check in the log that a new instance of every EntityPersistenceEventObserver listening to the save event is created again.

Note that same happens for the rest of events.
Proposed SolutionSet EntityPersistenceEventObserver as @ApplicationScoped and review all classes extending EntityPersistenceEventObserver to ensure that this change is safe.

related to issue 40046: remove final modifiers to avoid error on server startup

  Removed the final modifiers, now that the observers are @ApplicationScoped, the following error is raised on server startup in case they are final or if they have any final method: "org.jboss.weld.exceptions.UnproxyableResolutionException: WELD-001437 Normal scoped bean class is not proxyable because the type is final or it contains a final method"

fixes bug 40046: unnecessary objects created every time a DAL event is fired

  Declare EntityPersistenceEventObserver as @ApplicationScoped so that just one instance of every event handler is created by default. This is because being Dependent, a new instance of every event handler listening to a particular DAL event (save, update, delete, transaction begin, transaction completed) was being created.
