Timestamp in JPQL where clause issue

[wang yu]

Hello,
I met an OpenJPA Timestamp filed in JPQL where clause issue.
I used it as:
                EntityManagerFactory factory = 
Persistence.createEntityManagerFactory(
                                "test", System.getProperties());                
                String sql= "SELECT callpath FROM Callpath callpath WHERE
callpath.starttime > :from";
                Query query = factory.createEntityManager().createQuery(sql);
                query.setParameter("from", new
Timestamp(System.currentTimeMillis()), TemporalType.TIMESTAMP);
                query.getResultList();

The Exception stack:
<openjpa-1.2.1-r752877:753278 nonfatal user error>
org.apache.openjpa.persistence.ArgumentException: Encountered

And I noticed a bug track:
http://mail-archives.apache.org/mod_mbox/openjpa-dev/200801.mbox/%3c2013506.1200781234450.javamail.j...@brutus%3e

Has it been resolved? Or do I have a workaround?

Thanks!
