True, but it's not the base characteristics that I need to update; the
security packages aren't part of TINI's ROM, they're just loaded in by
TINIConvertor from the Java SDK, so updating the SDK will update the
packages. However, the update from _02 to _03 doesn't change the API, so it
would only have fixed the problem if it was actually an internal bug, which,
as it turned out, it wasn't.
I was able to get a little farther with the RADIUS client class by adding an
instance of the sun.security.provider.Sun class to the
java.security.Security class using the addProvider method. However, it still
couldn't load in MD5 because the sun.security.provider.MD5 class wasn't
loaded in by TINIConvertor. So, I eventually forced TINIConvertor to load in
that MD5 class by explicitly making an unused instantiation of it, and after
that the RADIUS client class worked.
For anyone looking for a RADIUS client java class for a TINI, this one was
called jradius and was in version 0.9.6

Remember that, from a pure Java structure point of view, TINI is JDK1.1.8
plus application specific extras.
You downloading JDK1.4 on your PC won't increase TINIs base Java
capabilities unless you start adding your own foundations to the TINI
classes.
Make sense?
