When I updated my CVS Kaffe source tree today and used it to restart
my Freenet node (stable branch), I got the following errors:

Since this same Freenet build worked with Kaffe before I updated
CVS, I suspect that a change in Kaffe is the immediate cause, but
I'm writing to both projects' lists just in case there is some
deeper problem in Freenet which is merely being exposed by a more
rigorous Java platform.

javax.servlet.ServletContext is part of the freenet-ext.jar file,
defined thus:

package javax.servlet;
public interface ServletContext {
    ...
    public void setAttribute(String name, Object object);
}

I don't understand why this error is occurring, given this definition.
It certainly looks all right to me.  So, being a simple but practical
person, I did a 'cvs -z3 update -dP -D "1 day ago"' (CVS/Tag =3D
D2003.04.17.23.42.42) and built that and used it.  Freenet then
started normally again.
