I'm not glad it happened, but glad that you experienced the same issue as me!

I think the Ant build was hiding the fact we do have three different
artifacts but managed to combine them into the same co-ordinates in
Maven Central.

Agreed.

My preference is option C if it is not too onerous, followed by option A.

Option C would appear the cleaner approach, but has the downside or
creating additional workload on a small team. Can we quantify how
difficult would it be to backport fixes?

If the structure of the projects is exactly the same it should be
possible to cherry-pick the commits. If we keep to a standard of using
JDK6-compatible code where possible the branches shouldn't drift too
far from each other. The other benefit is that the pom.xml will be
simpler without all the build profiles and multi-module build.

If not option A seems sensible and will allow us to publish complete
sources, javadoc and the artifact that all correspond to the spec
version.
