Perhaps the Hibernate bytecode transformer also needs to implement [https://asm.ow2.io/javadoc/org/objectweb/asm/ClassWriter.html#getCommonSuperClass-java.lang.String-java.lang.String-], as others have mentioned on [https://github.com/cglib/cglib/issues/117].

> Perhaps the Hibernate bytecode transformer also needs to implement [https://asm.ow2.io/javadoc/org/objectweb/asm/ClassWriter.html#getCommonSuperClass-java.lang.String-java.lang.String-], as others have mentioned on [https://github.com/cglib/cglib/issues/117].
