NullPointerException on transaction.rollback() in DbPersistenceService ---------------------------------------------------------------------- Key: JBPM-1465 URL: https://jira.jboss.org/jira/browse/JBPM-1465 Project: JBoss jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jPDL 3.2.3, SOA 4.2 CP02 Reporter: Martin Putz Assignee: Alejandro Guizar We are having NullPointerException from DbPersistenceService when Hibernate throws Exception on close() method. The line is transaction.rollback(); in rollback() method. My two cents is this code should be embraced with "if ( isTransactionEnabled && (transaction != null) )" statement, because we are using external JDBC Connection provider, and the transaction reference never be set. All calls to the rollback() method in DbPersistenceService are already preceded by a check for if ( (isTransactionEnabled) && (transaction!=null) ) { except this one after an exception has happened during the Hibernate session.flush call: Exception flushException = flushSession(); if (flushException!=null) { rollback(); // missing check if there is a transaction closeSession(); closeConnection(); throw new JbpmPersistenceException("hibernate flush failed", flushException); } -- 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
