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: A flaw in the address parser for the C++ messaging client caused numeric arguments for address attributes to be interpreted and encoded as strings. This resulted in problems when passing numeric arguments for queue-creation operations (e.g. setting the size limit, the durable journal file count, etc.). With this update, the parser has been fixed so that numeric text is interpreted as numbers and not strings.
