>                 Key: HHH-2604
>                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2604
>             Project: Hibernate3
>          Issue Type: Bug
>    Affects Versions: 3.2.4
>         Environment: Hibernate 3.2.2ga
>            Reporter: Tushar Pokle
>            Assignee: Diego Plentz
>            Priority: Minor
>
> A defect in Isolator.JdbcDelegate makes it throw the wrong exception - a NullPointerException -  that masks the true exception. In my case it was an UnsupportedOperationException("The user must supply a JDBC connection").
> The trouble is at the start of Isolator.JdbcDelegate.delegateWork(...):
> {code}
> 174		public void delegateWork(IsolatedWork work, boolean transacted) throws HibernateException {
> 175			Connection connection = null;
> 176			boolean wasAutoCommit = false;
> 177			try {
> 178				connection = session.getBatcher().openConnection();
> {code}
> If there is a failure opening a connection on line 178, the finally clause is executed. The finally clause needs the connection, which of course is null :-)
