Comparing bodyType and MAP_STRING_WILDCARD with '!=' instead of equals

[pavelzhur]

Hi!

I have such api:

@Headers("Accept: application/json")
public interface ApiWebService {
    @RequestLine("POST /campaign/add/")
    @Headers("Content-Type: application/x-www-form-urlencoded")
    GarsTelecomAddCampaignResponse addCampaign(Map<String, ?> request);
}

And builder like that:

HystrixFeign.builder()
                .setterFactory(new MyCommandConfiguration())
                .decoder(new GsonDecoder())
                .encoder(new FormEncoder())
                .target(ApiWebService.class, url);

When i'm trying to send request, i recieve such exception: Caused by: feign.codec.EncodeException: class java.util.HashMap is not a type supported by this encoder.

I think it's because of this comparison: if (bodyType != MAP_STRING_WILDCARD) in FormEncoder.encode method. Replacement this comparison by equals working fine.
