Foreign Key Constraint Issues Involving One-To-Many and Many-To-One Relationship in EcliplseLink2.1.2

I'm encountering a 1452 error on MySQL 5.5.9 while running some JPA tutorial code that I pulled off the EclipseLink website (http://wiki.eclipse.org/EclipseLink/Examples/JPA/EmployeeXML), and I'm hoping someone has some insight.

I'm using the latest stable build for EclipseLink as of today from the main website: eclipselink-jpa-modelgen_2.1.2.v20101206-r8635.jar and javax.persistence_2.0.1.v201006031150.jar.

When I populate the database via CreateDatabase.java, I get the following error:

com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Cannot add or update a child row: a foreign key constraint fails (jpatutorial.phone, CONSTRAINT FK_PHONE_EMP_PH_ID FOREIGN KEY (EMP_PH_ID) REFERENCES EMPLOYEE (EMP_ID)) Error Code: 1452 Call: INSERT INTO PHONE (PH_ID, TYPE, AREA_CODE, P_NUMBER, EMP_PH_ID) VALUES (?, ?, ?, ?, ?) bind => [25, Work, 613, 5558812, 23] Query: InsertObjectQuery(Phone([Work] 613 - 5558812))

The relevant models here are an Employee table and a Phone table. There is many-to-one relationship between Phones and Employees. Part of the orm.xml is below:

<entity class="model.PhoneNumber">
    <table name="PHONE" />
    <attributes>
    .
            .
        <many-to-one name="owner">
            <join-column name="EMP_PH_ID" />
        </many-to-one>
    </attributes>
</entity>

<entity class="model.Employee">
    <!--  secondary-table name="SALARY" /-->
    <attributes>
        <id name="id">
            <column name="EMP_ID" />
            <generated-value />
        </id>
        .
                    .
        <one-to-many name="phoneNumbers" mapped-by="owner">
            <cascade>
                <cascade-all />
            </cascade>
            <private-owned />
        </one-to-many>
              .
                      .
    </attributes>
</entity>

The code successfully creates the tables, creates address records for the employees, creates all the employee records, but then fails on inserting a phone record even though it has a valid FK reference to a employee record. I simplified the code so that it executes, persists and commits everything up to the point of the failure, but whether I execute the insert through JPA or manually by running a SQL script, I end up with the same 1452 error.

Interestingly, I found that if I dropped all the related Employee entities, and recreate them off create table definitions reversed engineered by MySQL workbench, I am able to successfully insert records into all the tables through JPA and manually via scripts. So, this suggests Eclipselink is creating the tables in some way that is producing a problem, and MySQL Workbench isn't capturing these problematic definitions in the reverse engineering. At this point, I'm out of ideas.
