Unexpected results if queries are used for embedded objects with RHDG

Issue

• assuming this playground project is used there are unexpected matches for a query. The query should only find an employee with a name AND the given age. Why it returns any result?

    Query from playground.Company c where c.employee.name = 'Wolf' and c.employee.age < 100  : found 1 matches
       Company[id=1, name='Red Hat, stock =true, employees 2]
         Employees:
           Person{id=1, name='Wolf, age='127, engaged='true, email=wf@redhat.com]
           Person{id=2, name='William, age='17, engaged='true, email=m@redhat.com]
