I guess I'm a little picky about warnings. I learned way back when
ANSI C was all the latest rage that ignoring them was not a good
idea.
Anyway, turns out the solution is to declare the dang thing:
public class HelloWorld extends HttpServlet {
static final long serialVersionUID = 0;
Now a C compiler (or lint) would have complained that it isn't
used. Sigh.
