Connection leak if the DBMS is not mapped into the ModifierFactory or if the DBMS does not support multiple connections ----------------------------------------------------------------------------------------------------------------------- Key: JBTM-532 URL: https://jira.jboss.org/jira/browse/JBTM-532 Project: JBoss Transaction Manager Issue Type: Bug Security Level: Public (Everyone can see) Components: JTA Affects Versions: 4.6.0, 4.5.0 Environment: Spring + JBossJTA Reporter: Mauro Molinari Priority: Blocker When a close() is issued on a ConnectionImple() before transaction termination (and this can happen because of Spring JTA infrastructure calling org.springframework.jdbc.datasource.DataSourceUtils.ConnectionSynchronization.beforeCompletion()) and either: - the ModifierFactory has no information about the DBMS in use (PostgreSQL, for instance...) or - the modifier for the DBMS says that it does not support multiple connections in a single transaction then, the synchronization that should close the connection after transaction completion is not registered and the connection is lost! This is at lines 349-359 of com.arjuna.ats.internal.jdbc.ConnectionImple in JBossTS 4.5.0 GA codebase. IMHO, the synchronization should always be registered unless we are sure that multiple connections in a single transaction are not supported. I have no idea of what should happen in the latter case... -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
