I'm using hibernate-envers 4.2.21.FINAL, I added to some properties the annotation @Audit(withModifiedFlag = true). The AUD table is correctly created, the _MOD colums also, but each time I update an entity, all the _MOD colums have the flag set to true, even if I don't have updated any (or just some) of the properties.

Is this a bug? Or maybe a wrong hibernate configuration?
Thanks
