hi Jerry,
I could not reproduce this problem and I am using the trunk level code.

Here is my test code snippet:
public void testRefreshOnDetachedEntity() {
try {
EntityManager em = emf.createEntityManager();
em.getTransaction().begin();
EntityA a = new EntityA();
a.setId(2);
em.persist(a);
em.flush();
em.detach(a);
em.refresh(a);
System.err.println("ERROR: No exception from em.refresh(detached)");
} catch (IllegalArgumentException e) {
e.printStackTrace();
System.out.println("SUCCESS: Refresh detached");
} catch (Exception e) {
e.printStackTrace();
System.err.println("ERROR: Unexpected exception from
em.refresh(detached): " + e.toString());
}
}

Subject: Refreshing detached entities
Possible gap in my understanding, but I would expect an exception in this case
based on section 3.2.5 of the JPA 2.0 specification: "If [entity] X is new,
detached, or removed entity, the IllegalArgumentException is thrown".
try {
TestEntity refreshDetached = new TestEntity("refresh detached");
em.persist(refreshDetached);
em.flush();
em.detach(refreshDetached);
em.refresh(refreshDetached);
logger.error("ERROR: No exception from em.refresh(detached)");
} catch (IllegalArgumentException e) {
logger.info("SUCCESS: Refresh detached");
} catch (Exception e) {
logger.error("ERROR: Unexpected exception from em.refresh(detached): " +
e.toString());
}
ERROR: No exception from em.refresh(detached)
