TRUNK-5068 Handling Exception

[madushan (Dileka Madushan)]

@dkayiwa I need to create a test method to catch the concept null exception. Should I go on to add a new Exception class.

TRUNK - 5068 Add tests to ProgramWorkFlowService

@suthagar23Could you please help me on this matter

Do you mind explaining why you would need to create a new exception class?

[suthagar23 (Suthagar Kailayapathy)]

@madushan Can you follow the try-catch method for the exceptions like the existing implementations?

@suthagar23 I will try them out. Thanks

@dkayiwa The reviewer asked me to use @Rule, and I modified the code accordingly. There would be no need to create a new class. Feel free to review on the changes.
