The setting `<property name="jboss.as.jpa.classtransformer" value="true"/>` for enabling bytecode enhancement has been supported for many years and will likely continue to be supported in the future.

This issue is about changing the default for `jboss.as.jpa.classtransformer` from false to true, which means applications will now need to opt out of (JPA/Persistence container managed) bytecode enhancement if they do not want their entity classes to be bytecode enhanced.

With this change, the Persistence container needClassFileTransformer will enable bytecode enhancement by default as per Hibernate ORM 6.2 defaults.
