Thanks for your help I had an "ah ha" moment. I know I read that the stack gets passed through twice, once down the stack and then back up but I had forgotten that. That was my problem. The exception was being thrown on the way back up the stack and being caught by the default ExceptionMappingInterceptor since it was lower in the stack.
I did as you suggested and defined my own default stack, replacing the exception interceptor with mine. Works great now. Thanks again for the help.
