Randy Casstevens kicked up what appears to be a very old bug in ECJ
indeed, in the (relatively unused) Lawnmower example. Frog.java
wasn't calling its subtree. That's probably ten years old.
This is a bug in a test application and not in an algorithm, so it's
much less of a concern experiment-wise. But I'm letting people know
just in case they want to re-run anything.
I've patched it on CVS but am posting it here too.
