Method annotated with @PreUpdade is not called
----------------------------------------------

                 Key: HHH-5722
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5722
             Project: Hibernate Core
          Issue Type: Bug
          Components: entity-manager
    Affects Versions: 3.6.0
         Environment: Java 1.6.0_21, Windows and Linux
            Reporter: Oleksandr Alesinskyy


I have a class with methods annotated  @PostLoad, @PrePersist, and @PreUpdate as below:
{code:title=Snippet}
    @Transient
    private B2BCustomerKeyPo b2BCustomerKey;
    @Embedded
    @AttributeOverrides( { @AttributeOverride(name = "username", column = @Column(name = "APPLICATION_NAME")),
            @AttributeOverride(name = "b2BCustomerName", column = @Column(name = "B2BCUSTOMER_NAME")) })
    private UserKeyPo applicationKey;
    ...
    @SuppressWarnings("unused")
    @PostLoad
    private void postLoad() {
        if (applicationKey != null) {
            if (applicationKey.getB2BCustomerName() != null) {
                b2BCustomerKey = new B2BCustomerKeyPo(applicationKey.getB2BCustomerName());
            }
            if (applicationKey.getUsername() == null) applicationKey = null;
        }
    }

    @SuppressWarnings("unused")
    @PrePersist
    private void prePersist() {
        if (b2BCustomerKey != null) {
            if (applicationKey != null) {
                if (!b2BCustomerKey.equals(new B2BCustomerKeyPo(applicationKey.getB2BCustomerName()))) {
                    final String msg =
                            String
                                    .format(
                                            "B2B customer [%s] of the product does not match the Application of the product [%s/%s]",
                                            b2BCustomerKey.getName(), applicationKey.getB2BCustomerName(),
                                            applicationKey.getUsername());
                    throw new IllegalStateException(msg);
                }
            } else {
                applicationKey = new UserKeyPo(b2BCustomerKey.getName(), null);
            }
        }
    }

    @SuppressWarnings("unused")
    @PreUpdate
    private void preUpdate() {
        throw new RuntimeException("§TEST§");
    }
{code}

prePersist and postLoad methods work as expected but preUpdate method is not called at all - while updated fields are dutifully written into DB (they never would if preUopdate will be called).


The code manipulating the object is as below:
{code:title=Snippet2}
        ProductPo productPoOld = readProductPo(input.getProduct().getProductKey().getExternalProductKey());
        ...
        B2BCustomerKey b2bCustomerKey = productNew.getB2BCustomerKey();
        productPoOld.setB2BCustomerKey(mappingHelper.mapObject(productNew.getB2BCustomerKey(),
                 B2BCustomerKeyPo.class));
        LOG.debug(productPoOld.getB2BCustomerKey());
        // @PreUpdate method is not called regardless if flush is present below or not
        productDao.flush();
{code}
