[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-2604) Isolator.JdbcDelegate masks the exception if it isn't possible to open a connection.

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 Pokle Assignee: Steve Ebersole Priority: Minor Fix For: 3.2.x, 3.3.0.CR2 Attachments: Patch-HHH-2604-trunk.txt 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 :-)
