Since I ran into the bug described in https://issues.apache.org/jira/browse/JCR-3425 JCR-3425, I'm using a recent 2.6-SNAPSHOT release built directly from source, deployed as *.rar. The whole thing runs on JBoss AS 7.1.1. My code is the following, with exception handling stripped: Repository repo = (Repository) new InitialContext().lookup("java:/project/jcr"); Session session = repo.login(new SimpleCredentials(user, "*".toCharArray()));   Node dir = session.getRootNode(); doSomethingWithTheInputStream(dir.getNode(...).getNode(Property.JCR_CONTENT).getProperty(Property.JCR_DATA).getBinary().getStream());   session.logout(); Upon calling session.logout, the following message appears in my log file whatsoever: 09:10:00,701 WARN  [org.jboss.jca.core.connectionmanager.pool.strategy.OnePool] (http--127.0.0.1-8000-14) IJ000612: Destroying connection that could not be successfully matched: org.jboss.jca.core.connectionmanager.listener.TxConnectionListener@6710ee[state=NORMAL managed
