Rather than allowing this ugly exception to occur, the profile service should mark these props as mandatory, since they obviously are, and it should also throw a friendlier exception when a mandatory prop has a null value when updateComponent() is called, e.g.:

Failed to update 'Queue Destination' managed component 'MyQueue' - cause: the property 'pageSize' is mandatory - a non-null value must be specified.

Here's the stack trace:
