you'll get that if you

• update the primary key of a parent record that had children OR
• delete a parent record that has children OR
• insert new child records that do not point to some parent record

at the time of commit. a deferred constraint deferrs checking until you commit -- when you commit the constraint must be satisfied. you are doing one of the three things above and then committing. Its supposed to work that way.
