Hibernate oneToMany Syntaxfehler

Hallo,
ich arbeite mich gerade in die oneToMany relation bei Hibernate ein. Ich erstelle Objekte vom Typ "Project" ein Project kann bei mir beliebig viele "Reports" haben. Die Dazugehörige Tabelle für die Assoziation wird von Hibernate Korrekt angelegt und beim ersten hinzufügen einer "Reports" klappt auch alles. Wenn ich allerdings einem "Project" einen weiteren "Report" hinzufügen möchte kriege ich einen Fehler:

Java:
@Entity
@Table(name = "TB_PROJECT")
public class Project implements Serializable {

  private static final long serialVersionUID = 1L;
 
  @Id
  @GeneratedValue(strategy = GenerationType.SEQUENCE)
  @Column(name ="PROJECT_ID", unique = true, nullable = false)
  private int projectID;
 
  @Column(name = "NAME", unique = false, nullable = false)
  private String name;
 
  @Column(name = "CLIENT", unique = false, nullable = false)
  private String client;

  @OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
  @JoinTable(name="PROJECT_REPORTS", joinColumns= {@JoinColumn(name="PROJECT_ID", referencedColumnName="PROJECT_ID")}
      , inverseJoinColumns= {@JoinColumn(name="REPORT_ID", referencedColumnName="REPORT_ID")})
  private List<Report> reportList = new ArrayList<Report>();

Java:
@Entity
@Table(name = "TB_REPORT", uniqueConstraints = {
        @UniqueConstraint(columnNames = "REPORT_ID") })
public class Report implements Serializable{
    
    private static final long serialVersionUID = 1L;
    
    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    @Column(name ="REPORT_ID", unique = true, nullable = false)
    private int reportID;
    
    @Column(name = "NAME", unique = false, nullable = false)
    private String name;
    
    @Column(name ="AMOUNT_COMPONENTS")
    private int amountComponents;
    
    @Column(name ="AMOUT_ACCEPTED")
    private int amountAccepted;
    
    @Column(name = "AMOUNT_REJECTED")
    private int amountRejected;
    
    @Column(name = "AMOUNT_DRAFT")
    private int amountUnderDevelopment;
    
    @Column(name = "AMOUNT_REVIEW")
    private int amountUnderReview;
    
    @Column(name = "TODELETE")
    private Boolean toDelete = false;

Folgender Code wird ausgeführt um ein Projekt und seine Assoziation zu updaten:
Das klappt auch beim ersten mal !
Sobald ich aber ein zweites Element in die Liste einfügen will kommt der Fehler.
Code:
@Override
    public void updatePersistentProject(Project project) {
        try {
            Session session = HibernateUtil.getSessionFactory().openSession();
            session.beginTransaction();
            session.saveOrUpdate(project);
            session.getTransaction().commit();
            session.close();
        } catch (HibernateException | IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

Code:
...

Hibernate: select nextval ('hibernate_sequence')
Hibernate: insert into TB_REPORT (REPORT_ID, AMOUT_ACCEPTED, AMOUNT_COMPONENTS, AMOUNT_REJECTED, AMOUNT_DRAFT, AMOUNT_REVIEW, NAME, TODELETE) values (?, ?, ?, ?, ?, ?, ?, ?)
Hibernate: update TB_PROJECT set CLIENT = ?, NAME = ?, TO_DELETE = ? where PROJECT_ID=?
Hibernate: update TB_REPORT set AMOUT_ACCEPTED = ?, AMOUNT_COMPONENTS = ?, AMOUNT_REJECTED = ?, AMOUNT_DRAFT = ?, AMOUNT_REVIEW = ?, NAME = ?, TODELETE = ? where REPORT_ID=?
Hibernate: update TB_REPORT set AMOUT_ACCEPTED = ?, AMOUNT_COMPONENTS = ?, AMOUNT_REJECTED = ?, AMOUNT_DRAFT = ?, AMOUNT_REVIEW = ?, NAME = ?, TODELETE = ? where REPORT_ID=?
Hibernate: delete PROJECT_REPORTS where PROJECT_ID=?

Er sagt mir dass ein "SyntaxFehler" in der Assoziations Tabelle vorliegt ?

Danke für jede Hilfe!
LG DirtyBit
 
Tatsächlich führe ich nie so ein Statement aus, es wird automatisch von Hibernate erzeugt und ich komme nicht drauf wieso. Schließlich tritt der Fehler erst beim einfügen des zweiten elements auf. Das erste wird problemlos erzeugt. Und bei zweiten mal wird genau der selbe Code ausgeführt , allerdings versucht hibernate dann irgendwas aus der Project_Reports tabelle zu löschen.
