I am writing a simple global debug listener to output CRUD debug events on 4 simple entities. In the entity mappings XML file, I have the following:

    
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm"
                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm
                                     http://java.sun.com/xml/ns/persistence/orm_2_0.xsd" version="2.0">
    <persistence-unit-metadata>
        <persistence-unit-defaults>
            <entity-listeners>
                <entity-listener class="bo.DebugListener">
                    <pre-persist method-name="prePersist"></pre-persist>
                    <post-persist method-name="postPersist"></post-persist>
                    <pre-remove method-name="preRemove"></pre-remove>
                    <post-remove method-name="postRemove"></post-remove>
                    <pre-update method-name="preUpdate"></pre-update>
                    <post-update method-name="postUpdate"></post-update>
                    <post-load method-name="postLoad"></post-load>
                </entity-listener>
            </entity-listeners>
        </persistence-unit-defaults>
    </persistence-unit-metadata>
</entity-mappings>


My DebugListener class just contains simple sys out calls as follows:



public class DebugListener {

    public DebugListener() {
        System.out.println(">>>>>>>>>>>>>>> CONSTRUCTOR");
    }

    public void prePersist(Object o) {
        System.out.println(">>>>>>>>>>>>>>> " + o.getClass() + " PREPERSIST");
    }

    public void postPersist(Object o) {
        System.out.println(">>>>>>>>>>>>>>> " + o.getClass() + " POSTPERSIST");
    }

    public void preUpdate(Object o) {
        System.out.println(">>>>>>>>>>>>>>> " + o.getClass() + " PREUPDATE");
    }

    public void postUpdate(Object o) {
        System.out.println(">>>>>>>>>>>>>>> " + o.getClass() + " POSTUPDATE");
    }

    public void preRemove(Object o) {
        System.out.println(">>>>>>>>>>>>>>> " + o.getClass() + " PREREMOVE");
    }

    public void postRemove(Object o) {
        System.out.println(">>>>>>>>>>>>>>> " + o.getClass() + " POSTREMOVE");
    }

    public void postLoad(Object o) {
        System.out.println(">>>>>>>>>>>>>>> " + o.getClass() + " POSTLOAD");
    }
}


I have 4 entities, several instances of which are inserted into an in-process Derby database (running in a Java SE environment), but the CRUD sys outs never get called. I do get 4 constructor sys outs, however.

Also, if I move the block of <entity-listener> XML into a section for any specific entity (under <entity class="...">), I do see all the CRUD sysouts for that entity. So it seems its a problem with the default listeners. I am thinking that the default entity listeners should be invoked on each and every entity registered into the persistence unit by default with the above XML and listener class.

Reproducible: Always

Steps to Reproduce:
1. Write some simple entity classes annotated with @Entity
2. Write a main method to instantiate a couple, and code to use an EntityManager to persist them to a Derby database using the embedded driver and the org.eclipse.persistence.jpa.PersistenceProvider. Declare a default entity listener in the entity-mappings XML file as shown above.
3. Run the Main class. The entities will be peristsed OK, but only the entity listener constructor sys out is called, not any of the pre and post persistence callback methods.
Note: running in a Java SE environment
