After HHH-9305 is fixed, it will be easier to workaround this bug by explicitly joining the to-one associations.

For example:
select e.lastName, e.department.deptName, e.title from Employee e

The workaround is to make one or both implicit joins explicit instead:
select e.lastName, e.department.deptName, e.title from Employee e inner join e.department
select e.lastName, e.department.deptName, e.title from Employee e inner join e.title
select e.lastName, e.department.deptName, e.title from Employee e inner join e.department inner join e.title
