Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: An empty list in the content of an address (i.e. []) caused the address parser to throw an exception. This could cause various operations (e.g. creating a messaging receiver) to fail. With this update, the address parser was fixed so that it can properly parse empty lists, thus, the aforementioned exceptions are no longer thrown.
