IMHO you are simply not sending your question to the set of people
that could answer them.  Based on your description the javac compilers
behave differently, but Ant doesn't.  I don't see how the Ant
developers might help you.

If you really think this is a bug in Ant, then please provide more
information about your setup (how does A depend on B and B depend on
C?).  A self contained build file would be best.

It would be good if you verified that running javac from the command
line shows a different behavior than Ant.
