Instances of `UnsupportedOperationError` being thrown when using StatelessSession and saving a ManyToOne have been addressed in this release of JBoss EAP 6. The error was caused by a call to `getTimestamp()` method which was not implemented for StatelessSession. The `UnsupportedOperationError` no longer presents.
