I had the same issue and I think I achieved what you wanted. You just have to override the canRead method of the form converter. With your example something like below should work.

FormHttpMessageConverter formConverter = new FormHttpMessageConverter() {
    @Override
    public boolean canRead(Class clazz, MediaType mediaType) {
        if (clazz == MyMultiValueMap.class) {
            return true;
        }
        return super.canRead(clazz, mediaType);
    }
};

And add this converter to your rest template.
