'java.lang.NoSuchFieldError' während der Verwendung der JPA

Ich erhalte die folgende Fehlermeldung beim Versuch aus dieser JPA tutorial:

Hier ist mein persistence.xml:

Person.java

   package entity;

    import javax.persistence.Entity;
    import javax.persistence.GeneratedValue;
    import javax.persistence.Id;
    import javax.persistence.Table;

    @Entity 
    public class Person {

        @Id
        @GeneratedValue
        private int id;
        private String firstName;
        private char middleInitial;
        private String lastName;
        private String streetAddress1;
        private String streetAddress2;
        private String city;
        private String state;
        private String zip;

    .
    .
    .
    (getters and setters)

Teil meiner JUnit-Test-Datei:

@SuppressWarnings("unchecked")
    @Test
    public void insertAndRetrieve() {
        em.getTransaction().begin();
        em.persist(p1);
        em.persist(p2);
        em.getTransaction().commit();

        final List<Person> list = em.createQuery("select p from Person p")
                .getResultList();
        System.out.println("here...");

        assertEquals(2, list.size());

Ich bin mit MySQL-db, die "person" - Tabelle wird in der Datenbank vorhanden. Und nach

em.getTransaction().begin();
em.persist(p1);
em.persist(p2);
em.getTransaction().commit();

Ich kann sehen, dass die zwei Datensätze eingefügt werden, die in der person-Tabelle. Aber auf die nächste Anweisung, es schlägt fehl.

EDIT 1:
Gläser in meinem build-path:

antlr-2.7.6.jar, 
commons-collections-3.1.jar, 
dom4j-1.6.1.jar, hibernate3.jar, 
hibernate-annotations-3.5.5-Final.jar, 
hibernate-commons-annotations-3.2.0.Final.jar, 
hibernate-entitymanager-3.5.5-Final.jar, 
hibernate-entitymanager-3.5.5-Final-sources.jar, 
javaee-api-5.0-3.jar, 
javassist-3.9.0.GA.jar, 
log4j-1.2.12.jar, 
mysql-connector-java-5.1.15.jar, 
slf4j-api-1.6.1.jar, 
slf4j-simple-1.6.1.jar, 
hibernate-jpa-2.0-api-1.0.0-CR-1.jar

Kann mir jemand sagen was ich falsch mache?

Dank.
