What is the impact of declaring a boolean variable VS declaring it as Boolean on Hibernate.
Is it handled differently by hibernate?

If you declare a variable as boolean (primitive type), hibernate will not be able to load a NULL value from the database. It will throw an exception like this:
Code:
Null value was assigned to a property of primitive type ...
So, you would probably use the primitive boolean type, if your mapped database column has a Not-Null constraint. Otherwise, you should prefer the Boolean object type.
