[Hibernate-issues] [Hibernate-JIRA] Created: (HHH-1744) BorrowedConnectionProxy does not support isClosed() operation

BorrowedConnectionProxy does not support isClosed() operation
-------------------------------------------------------------

         Key: HHH-1744
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1744
     Project: Hibernate3
        Type: Bug

  Components: core  
 Environment: hibernate 3.2.0.cr1, oracle9i
    Reporter: Roel Adriaensens


If you try to invoke the isClosed() method of a connection, the BorrowedConnectionProxy will call ConnectionManager.getConnection() which results in a HibernateException if the connection is closed.

stacktrace:
Caused by: org.hibernate.HibernateException: connection manager has been closed
	at org.hibernate.jdbc.ConnectionManager.getConnection(ConnectionManager.java:141)
	at org.hibernate.jdbc.BorrowedConnectionProxy.invoke(BorrowedConnectionProxy.java:40)
	at $Proxy131.isClosed(Unknown Source)
        ...

Relevant code (BorrowedConnectionProxy):

public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
		if ( "close".equals( method.getName() ) ) {
			connectionManager.releaseBorrowedConnection();
			return null;
		}
		// should probably no-op commit/rollback here, at least in JTA scenarios
		if ( !useable ) {
			throw new HibernateException( "connnection proxy not usable after transaction completion" );
		}
		try {
			return method.invoke( connectionManager.getConnection(), args );
		}
		catch( InvocationTargetException e ) {
			throw e.getTargetException();
		}
	}
