[hibernate-issues] [Hibernate-JIRA] Created: (HHH-5770) Memory leak when using hibernate 3.6 and jboss-4.0.3SP1

Memory leak when using hibernate 3.6 and jboss-4.0.3SP1 -------------------------------------------------------- Key: HHH-5770 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5770 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.6.0 Environment: hibernate 3.6, mysql server 5.0 and jboss-4.0.3SP1 Reporter: ran haim When hibernate runs hql statements for some reason it tries to load a class for every where statement token, and that class gets into jboss class loader black list and resource black list(that has no limit for some reason). Example: int userId = 4; String hql = "select from user where user.id = " + userId + " and user.type = 'admin'"; When hibernate will run this hql, it will try to load these classes and will fail (it is caught internally and handled, happens in WhereParser.doToken(line 412)) "4.class", "'admin'.class" and "and.class". This will lead for jboss to black list these classes (in a HashSet). This process leads over time to a big memory leak. I also think this still happens in newer jboss versions. -- 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
