Pande (Studies in the Origins of Buddhism, p. 73) remarks
that "sabbakammajaha" seems to be closer to the Jain persepective
that to the Buddhist.
Apparently it is now known that there are some verses -- I'm not sure
if this is one of them -- but there are some verses that occur in
similar forms in both Jain and Buddhist (and, for that matter,
Brahmanical) texts. So it's possible that widely-known sayings were
at some point mis-attributed to the Buddha, and eventually found
their way into the Pali canon (de Jong, A Brief History of Buddhist
Studies in Europe and North America, pp. 93-94).
Another possibility is that there was what Nakamura (Indian Buddhism,
pp. 57-60) calls an "Original Buddhism," which was quite different in
character from the systematic "Early Buddhism" we know from the four
homogenous Nikaaya-s.
