OpenJPA to handle new instances of the unenhanced type. If this is | |
invoked in a Java 6 environment, this method will redefine the methods | |
for each class in the argument list such that field accesses are | |
intercepted in-line. If invoked in a Java 5 environment, this | |
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 | |
instances after a flush has been called. | |
