Problem Solved...although I am still not getting any debug messages!
Here was the tip off: by changing NOTHING but the jar file I could make it
work (v4.6) or fail (v4.6.2). So I started inspecting variables.
Strangely, everything seemed correct in v4.6, but the projections kept
returning as Mercator in v4.6.2. After discovering that there were no
projections loaded and Mercator was merely the default, I found that I
needed to call ProjectionFactory.loadDefaultProjections().
Thanks for all the help!

I was wondering if the scale of the map projection matched the scales
required by the chart types you have.
If the maps worked before, they should work now.

I would focus on this. The fact that -Ddebug.rpf doesn't produce any
messages tells me the layer isn't active, it isn't being added to the
MapBean.
