invoked in a Java 6 environment, this method will redefine the methods

redefinition is not possible; in these contexts, when using field
access, OpenJPA will need to do state comparisons to detect any change
to any instance at any time, and when using property access, OpenJPA
will need to do state comparisons to detect changes to newly inserted
