Hi Kevin,
you guess was right. I disabled the cache in persistence.xml via :
<property name="openjpa.jdbc.QuerySQLCache" value="false"/>
After this the problems were gone. After that I changed it to "true"
again (just to double-checked) and was able to reproduce the problem again.
So smells like a bug. Should I open the jira issue ?
Bye,
Norman

Hi Kevin,
I will test it tomorrow when I have access to the server where I saw
the problem.
I will keep you updated as soon as I have some more info.
Thx,

I'm grabbing at straws here, but my first guess is that our caching of
prepared SQL queries is hitting a hiccup... To verify this, could you
temporarily turn off this cache (it's on by default) via the most convenient
method as documented here:
http://openjpa.apache.org/builds/2.0.1/apache-openjpa-2.0.1/docs/manual/manual.html#ref_guide_cache_querysql
Thanks!

Hi there,
we at JAMES use openjpa 2.0.1 as JPA Provider. Sometimes I see the

Which does not make any sense to me. The Statement is constructed as :
List<JPAVirtualUser> virtualUsers =
entityManager.createNamedQuery("selectMappings")
.setParameter("user", user)
.setParameter("domain", domain).getResultList();
Any idea what could be wrong ?
Bye,
Norman
