Re: [eclipselink-users] Eclipselink and CGLib-enhanced entity types
|
This works by default in the native API, but in JPA a check was added to
ensure the object's class was correct.
You can disable this check by using a DescriptorCustomizer or
SessionCustomizer to set,
descriptor.getInheritancePolicy().setDescribesNonPersistentSubclasses(true);
However, please log a bug for this, as this setting should not be on
inheritance policy, as it must be supported for descriptors without
inheritance as well. It should also be reconsidered to be disabled by
default, as CGLib and subclasses are quite common.
