Support for invoking the ModifyOperation from your own operation can be
tracked in SLING-1725. It will be in version 2.1.0 of the post servlets
module.
Incidentally, there is no release 2.0.5 of the servlets.post module.
2.0.5 is a development version. Sling module releases always end in even
numbers. You should ask whomever provided you with this JAR what
revision they built it against and, assuming this was prior to 990831
(when SLING-1703 was fixed), to give you an updated build. Or just build
it yourself.
