I would like to use the new "Cmp2.x jdbc2 pm".

I set the entity to use optimistic locking with version fields.
The application starts up and throws complains that the entity is missing the version field. This did not happen in other container configuration like the "Standard CMP2.x Entity". Is this a bug in the new "Cmp2.x jdbc2 pm" or should I declare those fields like any other CMP field in my entity?

Thanks,
Erez
