"org.hibernate.QueryException: could not resolve property" in JBoss EAP 6

Issue

• Three entities are linked by association
  • TestClass1 owns a OneToOne association with TestClass2 (through testClass2)
  • TestClass2 owns a OneToMany association with TestClass3 (through testClass3Set)
• A subquery with an implicit join included as a second condition in an outer query fails:

String query = "from TestClass1 as testClass1 where " +
    "testClass1.testClass2.title='test2' and " +
    "exists (from testClass1.testClass2.testClass3Set as testClass3 where testClass3.name = 'test3first')";
List a = hibernateSession.createQuery(query).list();
