> entity Footballer has composite primary key defined via @IdClass and @Id getters (see http://www.hibernate.org/hib_docs/annotations/reference/en/html_single/#entity-mapping-identifier)
> entity Goal has property 'footballer' defined via @ManyToOne
> query
>   select g from Goal g where g.footballer in (select f from Footballer f where f.age=22)
> is translated to erroneous SQL
>   select goal0_.id as col_0_0_ from tgoal goal0_ where (goal0_.fb_firstname, goal0_.fb_lastname) in (select (footballer1_.fb_firstname, footballer1_.fb_lastname) from tfootballer footballer1_ where footballer1_.age=22)
> it's strange, but the slightly modified query
>   select g from Goal g where g.footballer.id in (select f.id from Footballer f where f.age=22)
> is translated to valid SQL
>   select goal0_.id as col_0_0_ from tgoal goal0_ where (goal0_.fb_firstname, goal0_.fb_lastname) in (select footballer1_.fb_firstname, footballer1_.fb_lastname from tfootballer footballer1_ where footballer1_.age=22)
