        Key: HB-295
    Summary: Session.refresh leaves old data in JCS cache
       Type: Bug

     Status: Unassigned
   Priority: Minor

    Project: Hibernate2
 Components: 
             core
   Versions:
             2.0.2

Description:
http://sourceforge.net/forum/message.php?msg_id=2078891

Session session = sessionFactory.openSession();
Foo foo = session.load(Foo.class, id); // (1)
// Now execute SQL via JDBC (not Hibernate) that changes the data from which foo is mapped.
// (2) workaround: sessionFactory.evict(Foo.class, id);
session.refresh(foo); // foo is copied from the database
session.close();

session = sf.openSession();
Foo foo2 = session.load(Foo.class, id);
// At this point, foo2 contains different data than foo.
// foo2 contains the old data that foo contained at (1) above.
session.close();

foo2 should contain the new data, just like foo.  Ideally, session.refresh() would copy the new data into the cache.  At least, it should invalidate the old cached data.

One can work around this problem, by calling sessionFactory.evict at (2) above.
