CGLIB Enhancement failed error with signed jars ----------------------------------------------- Key: HHH-900 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-900 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.0.1 Environment: Hibernate 3.0.1 hsqldb Reporter: James Weiss Attachments: labB.zip I just recently attended the Hibernate training course in Chicago. Andy Oliver, the instructor, asked me to add this deffect. When I add the POJO files for persistence to a signed jar, the following error is thrown: 12:19:42,587 ERROR BasicLazyInitializer:103 - CGLIB Enhancement failed: org.hibernate.auction.model.CreditCard To recreate this problem, I modified the labB exercise from the class to create a signed jar. The build.xml file now has both a "test" and a "testsigned" target. If you run "ant test" the unsigned jar is used and the program runs fine. If you run "ant testsigned", the signed jar is used and the test throws errors.
