Because of some kind of bug in hibernate-tools, the generated scripts may differ even when the annotations are the same. Strictly speaking it's not really a bug because the differences are simply in the order of some columns/constraints, or in other words the scripts are still "correct", but it's kind of annoying when the generated script is version controlled. You can either discard the change (by doing a svn revert on that file) or commit it. Either way it doesn't really matter.
