[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-2447) Connection leak if logAndClearWarnings throws

Connection leak if logAndClearWarnings throws ---------------------------------------------- Key: HHH-2447 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2447 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.1.3, 3.2.2 Environment: Database product name : DB2/NT Database product version : SQL08025 JDBC driver name : IBM DB2 JDBC Universal Driver Architecture Hibernate 3.1.3 (seems to exist in 3.2.2 as well) JDBC driver version : 2.9.31 Reporter: Jeppe N. Madsen Assignee: Strong Liu Priority: Minor In ConnectionManager.closeConnection, logAndClearWarnings is called before connection.close() is called. If this call throws an exception, the connection is never closed. We have observed that DB2 sometimes throws an Error because the SQLWarning chain is wrong: [14-02-07 11:36:30:889 CET] 10b0b533 WebGroup E SRVE0026E: [Servlet Error]-[SQLWarning chain holds value that is not a SQLWarning]: java.lang.Error: SQLWarning chain holds value that is not a SQLWarning at java.sql.SQLWarning.getNextWarning(SQLWarning.java:109) at org.hibernate.util.JDBCExceptionReporter.logWarnings(JDBCExceptionReporter.java:50) at org.hibernate.util.JDBCExceptionReporter.logWarnings(JDBCExceptionReporter.java:33) at org.hibernate.util.JDBCExceptionReporter.logAndClearWarnings(JDBCExceptionReporter.java:22) at org.hibernate.jdbc.ConnectionManager.closeConnection(ConnectionManager.java:443) at org.hibernate.jdbc.ConnectionManager.cleanup(ConnectionManager.java:379) at org.hibernate.jdbc.ConnectionManager.close(ConnectionManager.java:318) at org.hibernate.impl.SessionImpl.close(SessionImpl.java:293)
