[hibernate-issues] [Hibernate-JIRA] Created: (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
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 :-)
