Chin Hsu commented on HHH-3002:
-------------------------------

I don't know if you use reverse engineering tool to generate the hbm.xml but I did and have the exact same exception trace.  for a database table with a column named version, the generated hbm will have the field defined in a version element:

        <version  name="version" type="string">
            <column name="VERSION" length="20" />
        </version>

when it should be:

        <property  name="version" type="string">
            <column name="VERSION" length="20" />
        </property>

manually fix the hbm.xml file solves the problem.  I think this maybe a bug on the reverse engineering tool?
