So, what are the values of the projection when you expect to see RPF
data, and what kind of RPF data do you have?
* Sorry, I don't understand. We have a bunch of disks from NIMA/NGA in my
lab, and we just started using those. Since this "just worked" in v4.6, we
never questioned it. The maps cover much of the eastern seaboard, so I
expect to see maps all around 37N 77W (southern Maryland) at most map
scales. I tried reverting back to the deprecated projection code and that
does not work either.

-Ddebug.rpf
If you aren't seeing any messages from that, then it sounds like the
layer isn't getting connected to the map. Are you adding a
LayerHandler to the MapHandler? That's the thing that connects the
layers to the MapBean, depending on their visibility.
* Before adding any layers to the mapHandler, I add a LayerHandler. Just to
make sure I am rendering layers, I added one of my custom layers and I am
able to see the data it renders to the screen. In addition, I created a VPF
Layer, and aside from some error messages, it too appeared to work. I add
the vpfLayer with the same calls (except for also calling vpf's load
function). Regardless of using the -Ddebug.rpf, Debug.output and
Debug.error messages are printed.

I don't know what these are.
* Swing stuff that I found while browsing JavaDoc. They are supposed to do
various debug things -- grasping at straws here to get any good debug info.

Do you have any other indication that the layer is being added to the
MapBean? LayersMenu, LayersPanel?
* If I fail to supply a path name or supply a wrong path name, I do get an
error from RpfLayer. My application does not have any layer control GUI's.
