JDBC Connection leak with Postgres ---------------------------------- Key: JBTM-2667 URL: https://issues.jboss.org/browse/JBTM-2667 Project: JBoss Transaction Manager Issue Type: Feature Request Components: JTA Affects Versions: 5.3.2.Final Reporter: Alexis Hassler Assignee: Tom Jenkinson Fix For: 5.next When using Narayana's JDBC TransactionalDriver with a Postgres XA datasource, the connections are never closed. The problem can be workarounded by adding a modifier : {code:java} ModifierFactory.putModifier ("postgresql native driver", -1, -1, PsqlConnectionModifier.class.getName()); {code} With a modifier, the close method is called on the XAConnection object, with no modifier it's called on the Connection object.
