> org.apache.jdo.tck.query.jdoql.NullCollectionsAndIsEmpty uses its localSetUp() method
to null the projects of an Employee.  However, the Employee.projects field uses mapped-by
in its mapping, and per section 15.3 of the JDO 2 spec, that means changes to it aren't reflected
in the datastore.  To fix, add the following lines after retrieving "emp1" but before nulling
its projects in localSetUp():
>         for (Iterator itr = emp1.getProjects().iterator(); itr.hasNext();)
>             ((Project) itr.next()).removeMember(emp1);
