[hibernate-issues] [Hibernate-JIRA] Created: (HHH-5166) Inconsistent session state with merge/evict on cascade="all" association

Inconsistent session state with merge/evict on cascade="all" association ------------------------------------------------------------------------ Key: HHH-5166 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5166 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.1, 3.3.2 Environment: Reproducted on : Hibernate-core 3.3.2 and 3.5.1-Final DB2 and HSQL DB with annotation and classic hbm mapping Reporter: Alexandre FRADIN Priority: Critical Attachments: hibernate-test-merge-evict-cascade-all.zip My apologies for my English. I have entities User and Role with a many-to-many association mapped with cascade="all". So merge and evict operations on User should be applied to this association. When I do the following : 1) create user u existing in DB 2) add a new Role r to this user (this Role don't exists in DB) 3) merge u 4) evict the instance returned by the merge operation 5) use the same session for any operation 6) commit the session I get this exception : "org.hibernate.AssertionFailure: possible nonthreadsafe access to session". There is no thread issue. I think this is a standard way to use merge and evict operations. I think that merge and evict operations used on modified entities leave the session in an inconsistent state. See unit test wich reproduct this bug. Does a workaround exist for this bug?
