I have created a TestCase to show the problem. It completes through to the end.
Please let me know if you manage to find a solution/fix.
/**
| * [JBPM 3.2.1]
| * This TestCase should show that the when a variable it set to required,
| * the taskInstance is still able to complete, even when said variable is
null.
| * Calling taskInstance.end() does not throw an exception.
