won't.

            I have one idea for a better approach, but it's painful, and I haven't tested it: We
            could postprocess Collect.gwt.xml to add <skip> lines for all the files that should be
            covered by testModule.gwt.xml. Maybe I'll try it someday.

            for (ValueSource vs : valueSources) {
                interpolator.addValueSource(vs);
            }

            for (InterpolationPostProcessor postProcessor : postProcessors) {
                interpolator.addPostProcessor(postProcessor);
            }

            try {
                try {
                    result = interpolator.interpolate(result, recursionInterceptor);

        for (ValueSource vs : valueSources) {
            interpolator.addValueSource(vs);
        }
        for (InterpolationPostProcessor postProcessor : postProcessors) {
            interpolator.addPostProcessor(postProcessor);
        }
        RecursionInterceptor recursionInterceptor = createRecursionInterceptor(request);
        return value -> {
