I've recently upgraded my MySQL RDBMS from 4.0 to 4.1. MySQL 4.1 crashes while JBoss is inserting objects that have relationships with other database objects. I've tried Jboss 3.2.1 and 3.2.3. Has anyone successfully used JBoss with MySQL 4.1? Is so, was there any configuration/settings that differed from 4.0, with either JBoss or MySQL?
