Hibernate bytecode transformer needs to pass classloader into ASM ClassWriter to avoid ClassNotFoundException that causes super classes to be ignored if in a different classloader ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: WFLY-12596 URL: https://issues.jboss.org/browse/WFLY-12596 Project: WildFly Issue Type: Bug Components: JPA / Hibernate Reporter: Scott Marlow Assignee: Scott Marlow Priority: Major Fix For: 19.0.0.Beta1 Some users have reported seeing warnings like: {quote} WARN [org.jboss.modules.define] (MSC service thread 1-4) Failed to define class BGP in Module "deployment.mine.ear" from Service Module Loader: java.lang.ClassFormatError: Failed to link SuperClassInDifferentEarClassLoader (Module "deployment.mine.ear" from Service Module Loader): Type EntityBean not present {quote} Where class SuperClassInDifferentEarClassLoader, is a super class that is contained in a different EAR classloader than the subclass. The workaround should be passing the classloader to use in to the ASM ClassWriter class, by extending the ClassWriter class and providing an implementation of getClassLoader() method. {code}
