> One can think that by specifying e.g. MatchMode.START in a "like" restriction Hibernate takes care of escaping SQL LIKE wildcard characters in the supplied pattern. It doesn't, actually Hibernate only inserts a % before the first character.
> I am not sure what was the intent of the original author (Gavin King), so the issue may only be missing documentation. However I don't see any other useful purpose of this class then providing database independent escaping. It seems that all databases use the % wildcard, so there is no need to provide database indpeendence to that.
> It can be argued that this might create a security problem for an unaware developer, so I set issue type to bug.
