IIRC only digits between dots are interpreted as numbers and will be
compared as numbers
With dashes values are concatenated as a String and hence will be compared
as Strings.
So dots and dashes have a different effect.
Here you can find a huge number of tests that should cover it:

Sorry, I didn’t mean that the spec explicitly states an example that:

I meant that the algorithm described in the spec results in that outcome.
ComparableVersion correctly outputs that for the comparison between
1-0-2 &
1-1.
Both my original & my revised proposed change to the spec would result
in:
1-0-2 = 1-0-2 < 1-1
Which I think makes more sense.
My original proposal would have resulted in:
1-0-rc = 1-0-rc
But my revised proposal results in:
1-0-rc = 1-rc
Which accords with the existing spec, so my revised proposal improves
upon
my original proposal.
Throughout this email, the syntax for = is:
original = canonical

I don't recognize this. Can you quote from that page?
