Given this HQL:

"select p, p.department from Person p left outer join p.department"

I would expect to get results for Person's who have a null department ID.

But instead the generated SQL is adding an inner join clause, filtering out those Persons without a department.

select
person0_.ID as ID1_1_0_,
department2_.ID as ID1_0_1_,
person0_.NAME as NAME2_1_0_,
person0_.DEPARTMENT_ID as DEPARTME3_1_0_,
department2_.NAME as NAME2_0_1_
from
PERSON person0_
left outer join DEPT department1_ on person0_.DEPARTMENT_ID=department1_.ID
inner join DEPT department2_ on person0_.DEPARTMENT_ID=department2_.ID

That second inner join seems incorrect.

This seems to be similar, if not the same as
