Isolator.JdbcDelegate masks the exception if it isn't possible to open a connection.
------------------------------------------------------------------------------------

                 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
            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 :-)
