using JBoss 4.0.2 with default hibernate (3.0)

Hibernate version: 3.0

Mapping documents:

Code between sessionFactory.openSession() and session.close(): using JTA transaction -
SessionFactory factory = this.getSessionFactory(JNDI_NAME);
return factory.getCurrentSession();

Name and version of the database you are using: PostgreSQL 8.0


in on of my .hbm.xml files have the following query defined:

<query name="getMyTasks"><![CDATA[
from com.my.task.TaskDO task
where task.status=com.my.task.TaskStatus.NEW
and (task.cancellationStatus=com.my.task.CancellationStatus.CANCELLATION_REQUESTED
or task.cancellationStatus=com.my.task.CancellationStatus.FORCE_CANCELLED)

]]>
</query>


TaskStatus.NEW, CancellationStatus.CANCELLATION_REQUESTED, and CancellationStatus..CancellationStatus are referencing "public static int"
which worked fined with hibernate 2.1, but now I'm getting exception starting JBoss:



Full stack trace of any exception that occurs:

what I found is that somehow an error is being generated in
HqlBaseParser->statement() method being called from QueryTranslatorImple->parse(..) method, but if I change the name of a public static variable that is being referenced in the query from
com.my.task.TaskStatus.NEW to com.my.task.TaskStatus.NEW_S it works fine. I couldn't debug it further since I couldn't find source for "org.hibernate.hql.antlr.HqlBaseParser"

Any idea on why that is, is it a special keyword?
