Cannot determine java-type from given member [null] --------------------------------------------------- Key: HHH-4870 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4870 Project: Hibernate Core Issue Type: Bug Components: entity-manager Affects Versions: 3.5.0-Beta-4 Environment: jdk 6u18 glassfishv3 Reporter: Marcial Atienzar Attachments: eclipse.debug, Empre.java, hibernate.cfg.xml, persistence.xml, Prcontra.java I've tested to migrate from hibernate 3.3.2 to 3.5.0 Beta4. I've remove all hibernate*.jar from classpath and add only de hibernate3.jar I've downloaded the source off hibernate-entitymanager to debug from eclipse. I've reached the class that has the error, but I don't know what can I do to resolve it. I'm doing something wrong? I attatch the sources of the classes that takes part on eclipse debug. I don't know how to attach a testcase. The project has more than 200 entities. I've post previously in hibernate forums: https://forum.hibernate.org/viewtopic.php?f=1&t=1002363&p=2424419...
