Well, my interceptor class gets called and it looks to me like the
Handler's initArgs get set with a 'classdebuginfo' entry. That also
seems to be the right parameter name in EmbededServletOptions which is
what the SunJavaCompiler seems to be looking at. Not sure how the
Options gets it from the Handler.
However, it's still not working for me.
I'm going to try 3.3 and if that fails, I'll roll my own Tomcat and
force the -g...
Thanks,
Chris
