HQL part of this issue is done as i know - but is there any progress on Criteria API development?
I mean Criteria API for JOIN ON <expression> logic... 

Is this issue fixed, if so, where is the patch and when will it be added/provided by Hibernate themselves?

> It would be nice to be able to do explicit joins on unrelated classes with HQL:
> (hope this renders correctly)
>           select empl, phone
>             from org.example.Employee empl
>  left outer join org.example.PhoneBook phone
>               on phone.lastName = empl.lastName
>              and phone.firstName = empl.firstName
>            where empl.salaryGrade > 10
> Note that this would also implicity solve HB-1089 because you could list join criteria that match what Hibernate would have chosen anyway (i.e., list a many-to-one relationship as a criteria explicitly).
> Syntactically this could be disambiguated from the existing join syntax because the token after "join" is a class name rather than a property name.
