Steve Ebersole ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-16572 ( https://hibernate.atlassian.net/browse/HHH-16572?atlOrigin=eyJpIjoiYmVjZD... ) Re: Incorrect enhancement for PROPERTY attributes with mismatched field and method names ( https://hibernate.atlassian.net/browse/HHH-16572?atlOrigin=eyJpIjoiYmVjZD... ) I ran into a problem I just cannot understand. The problem seems isolated to the BytecodeEnhancerRunner JUnit Runner we use to test enhancement, though I cannot explain it. Hoping someone can help? java.lang.ClassCastException: class org.junit.internal.runners.ErrorReportingRunner cannot be cast to class org.junit.runners.ParentRunner (org.junit.internal.runners.ErrorReportingRunner and org.junit.runners.ParentRunner are in unnamed module of loader 'app') If not, I think I’ll take you up on your offer Rafael. What confuses me is that ByteBuddy does not load Class references into any classloader, so I am not sure how using ByteBuddy has this affect at all. The basic change I made is, when enhancing a class ( Enhancer#enhance ): * Load its super TypeDescription ref, if one * Load its FieldDescription refs * Load its MethodDescription refs ( https://hibernate.atlassian.net/browse/HHH-16572#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16572#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
