I'm currently struggling with Hibernate 3.1.1 to which our app is being
migrated from 3.0.5. There is a major problem with transactions which seem
to be working not exactly as they were. I'm moving the system from MySQL
4.1.x to 5.0.x and J/Connector from 3.1.0 to 3.1.13 also. That's a lot of
unknown factors but perhaps someone had similar problem? Here's a piece of
code I'm trying to run:

/*
Start a time consuming procedure which with God's help produces a sales
report
*/

Transaction t = null;
Iterator it = null;
Object [] row = null;
