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. The answer is: most tests pass. What fails is this test (Apache 2.0 license, BTW)
public void testDetachedObject() throws Exception {
Event event = createTestEvent();
session.save(event);
session.flush();
closeSession();
//here the event is detached.
//we change it outside an operation.
String text = "modified";
event.setText(text);
session = getSessionFactory().openSession();
Event merged=(Event) session.merge(event);
assertEquals(event, merged);
session.flush();
closeSession();
session = getSessionFactory().openSession();
Event loaded = (Event) session.load(Event.class, event.getKey());
assertEquals(text, loaded.getText());
assertEquals(event, loaded);
}
the session.load operation is failing, with the short stack trace of:
java.lang.NullPointerException

The root cause is probably contained in the info that gets printed when the session starts up, complaining that things cant be added to sealed classes

No doubt there is some way to configure hibernate to create proxies in a different package, and I shall seek that option out. All I want to note here is that NPEs are not the best way to report failure.

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1365?page=comments#action_23439 ] Martin Schulz commented on HHH-1365: ------------------------------------ I'm running into the exact same issue...

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1365?page=all ] Martin Schulz updated HHH-1365: ------------------------------- Attachment: cglib-src-2.1_3.patch This patch for cglib-2.1.3 allows the Enhancer to create the new class always under the ProtectionDomain of the parent. I'm not sure what actually went wrong here, but definitely the requirement to sign the cglib jar file and/or remove the signature from case to case when testing was getting pretty annoying. So the patched cglib.jar is meant to work either way. > 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 > Attachments: cglib-src-2.1_3.patch > > > I'm testing what happens to hibernate when running against a signed JAR.
