Hibernate51CompatibilityTransformer#transform should always return null if no class change is made -------------------------------------------------------------------------------------------------- Key: WFLY-10856 URL: https://issues.jboss.org/browse/WFLY-10856 Project: WildFly Issue Type: Task Components: JPA / Hibernate Reporter: Scott Marlow Assignee: Scott Marlow Fix For: 14.0.0.CR1 Currently, Hibernate51CompatibilityTransformer#transform is not always returning null when no changes are made to the application class, which could slow application deployment. This only happens for Hibernate ORM native applications that extend/implement certain ORM classes but do not require class transforming. We did not measure the performance impact, so not sure how important this change is.
