[hibernate-issues] [Hibernate-JIRA] Created: (HHH-3220) Patch to prevent "org.hibernate.AssertionFailure: possible non-threadsafe access to the session" error caused by stateless sessions

Patch to prevent "org.hibernate.AssertionFailure: possible non-threadsafe access to the session" error caused by stateless sessions ----------------------------------------------------------------------------------------------------------------------------------- Key: HHH-3220 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3220 Project: Hibernate3 Issue Type: Patch Components: core Affects Versions: 3.2.6 Environment: Hibernate 3.2.6, Apache Derby on Mac OSX & PC Reporter: Dan Bisalputra Priority: Minor When performing a query in a stateless session, the query loads objects in a two-phase process in which a temporary persistence context is populated with empty objects in the first phase, then the objects' member data are read from the database in the second phase. If one of the objects contains an association or a collection, it performs a recursive call to the session's get() method. The get() method clears the temporary persistence context, so if the parent object contains any other associations to be read in the second phase, Hibernate throws an assertion because they are not found in the persistence context. This patch solves the problem by only clearing the persistence context when the recursion ends. It passes all the unit tests for our application, but I have not tested it with any of the Hibernate unit tests. -- 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
