Workaround for bug in PostgreSQL JDBC driver
--------------------------------------------
Key: HHH-2699
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2699
Project: Hibernate3
Issue Type: Improvement
Affects Versions: 3.2.3
Environment: Hibernate 3.2.3, PostgreSQL 8.2.4 (Mac OS X), JDBC driver 8.2 Build 505 (JDBC 3)
Reporter: Matt Solnit
The following line (103) in org/hibernate/connection/DriverManagerConnectionProvider.java:
if (isolation!=null) pooled.setTransactionIsolation( isolation.intValue() );
causes an exception when using the PostgreSQL JDBC driver, because it does not allow you to change the transaction isolation level once a connection is in use. However, their implementation does not handle the fact that the isolation level is really not being changed in this case (because it is being set to the existing value).
The following change would work around this issue:
if ( isolation!=null && pooled.getTransactionIsolation()!=isolation.intValue() ) pooled.setTransactionIsolation( isolation.intValue() );
P.S. I know the DriverManagerConnectionProvider is not for production use, but we use it in development :-).
