AbstractStoreManager.flush() doesn't take into account of
Write-locked but unchanged entities
Hi,
I am writing a JPA provider for IBM U2 by extending the
AbstractStoreManager. According to the OpenJPA doc and other sources such
as
http://java.sun.com/javaee/5/docs/api/javax/persistence/LockModeType.html,
the following code should force a version update on the CUSTOMER entity. But
it doesn't. Further examination of the AbstractStoreManager.flush() found
that it doesn't check if a SM requires a version update. I am wondering if
this is by design or a overlook in implementatoin. Please advise.
em.getTransaction().begin();
CUSTOMER cust = em.find(CUSTOMER.class, "9");
em.lock(cust, LockModeType.WRITE);
em.getTransaction().commit();
Thanks,
Jianfeng Mao
