I have found the problem.
The contractor who originally ported our customizations from CAS 2 to
CAS 3 was attempting to fix a problem that did not exist. He was just
using the spring webflow inappropriately. He seemed to be attempting to
get around a problem with his custom login jsp, where the username field
was not filled in after a login failure. He ended up removing the
generateLoginTicket piece. I think that ended up being the problem.
Nothing showed up because we don't use the proxy capability.
Anyhow, as far as I can tell, none of his changes to login-webflow.xml
were needed, except for our small plugin, which I have made a single
line change to incorporate. So, I'm kind of happy we ran into this
problem, because we now have a login-webflow.xml that is identical to
JASIG CAS stock, except one line. :D

Hi Guys,
Okay, looking at the source with a stack trace doesn't help me. I'm
betting spring is mangling the stack trace like it usually does. I've
seen this happen on other projects. What a nightmare. :P
Can anyone make sense of this stack trace? I'm sure there's no code on
line 1 of CentralAuthenticationServiceImpl.java :D
