The original implementation assumed that the UUIDs were coming through a strings, but this was changed at some point to use the 16-byte UUID format straight out of MSF. This was causing issues when UUIDs had null bytes in them because the UUID was being truncated and the result was that UUIDs that were being parsed in MSF were too small, resulting in exceptions.
