Problem locking an proxy to session when an detached proxy is already on its persistence context ------------------------------------------------------------------------------------------------ Key: HHH-5871 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5871 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.6.0 Environment: web app over tomcat using hibernate version 3.5.6-Final and spring.version 3.0.5.RELEASE with SpringWebApplicationFactory configured as an filter on web.xml Reporter: pedro santos Attachments: stackTrace.txt, test-fix.patch Problem locking an proxy to session when an detached proxy is already on its persistence context The call: session.lock(proxy, LockMode.NONE) is throwing: org.hibernate.TransientObjectException: Proxy is detached (i.e, session is null). The read-only/modifiable setting is only accessible when the proxy is associated with an open session. The problem is that I'm not able to lock an proxy on session due an old detached proxy already add on its persistence context. I'm sending an test case demonstrating the bug, plus the fix on TwoPhaseLoad to don't test lazyInitializer ready only property when it is not available. What is weird on all this problem is: how did an detached proxy get in another opened session? I'm simulating it on the test case, but my application code don't even look like it. I created the test case only by analyzing the exception stack trace. This problem is happening time to time and crash the production app. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
