What am I missing here?

Isn't that just a warning and not an error? ecj is a little more particular than other bytecode compilers WRT serialVersionUIDs IIRC.

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.

Thanks
