[JBoss JIRA] Created: (HIBERNATE-46) Javassist lazy proxy factoring not thread-safe

by Ortwin Glück (JIRA)

Javassist lazy proxy factoring not thread-safe ---------------------------------------------- Key: HIBERNATE-46 URL: http://jira.jboss.com/jira/browse/HIBERNATE-46 Project: Hibernate Issue Type: Bug Environment: JBoss AS 4.0.4 with EJB 3-RC8 Reporter: Ortwin Glück Assigned To: Steve Ebersole Multiple threads may simultanously (especially on SMP systems) create proxy classes for the first time. The JavassistLazyInitializer is not completely thread safe. So the first thread will successfully create the dynamic class, while a second thread may fail. We saw this happen a few times at JBoss startup when multiple messages from other systems arrived via JMS (quite normal when you take your PROD system down for some minutes, as work keeps queuing up). So multiple MDB threads were running the same transactions (using the same classes) and thus the probability for this error to occur is close to 100%. The situation can easily be solved by proper synchronization inside the JavassistLazyInitializer.

Plus, I'd like to change this to use the PropertyManager anyway. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

TaskConversationContext or TASK scope ------------------------------------- Key: JBSEAM-382 URL: http://jira.jboss.com/jira/browse/JBSEAM-382 Project: JBoss Seam Issue Type: Feature Request Components: BPM Reporter: Gavin King Assigned To: Gavin King Fix For: 1.1 We could support an alternative implementation of the conversation Context where variables get saved not to the HttpSession but to the jBPM database. This would mean that the work in progress could be recovered by the user. Alternatively, we could have a special TASK context. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
