[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1365?page=comments#action_22202 ] Juozas Baliuka commented on HHH-1365: ------------------------------------- Sign jars and classes using same signature (probably application classes are unsingned) > NPE AbstractEntityTuplizer.createProxy(AbstractEntityTuplizer.java:372) when trying to load a class defined in a signed/sealed JAR > ---------------------------------------------------------------------------------------------------------------------------------- > > Key: HHH-1365 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1365 > Project: Hibernate3 > Type: Bug > Versions: 3.1 > Environment: Java1.5.06 Ant1.7alpha, hibernate 3.1 > Reporter: Steve Loughran > Priority: Minor > > > I'm testing what happens to hibernate when running against a signed JAR.
