Jersey Client: too many Conent-Type header values

in my web application I invoke a service like this:

Response response = null;
Builder builder = webTarget.request().accept(MediaType.APPLICATION_JSON_TYPE);

if (this.headers != null) { 
    builder.headers(this.headers); // headers is empty in this case
}

response = builder.method(methodName.toString(), Entity.entity(multiPart, multiPart.getMediaType()), Response.class);

if (typeOfT.equals(Response.class)) {
    return (T) response;

} else {
    handleException(response);
    return gson.fromJson(response.readEntity(String.class), typeOfT);
}

The service responds correctly but when I try to deserialize the response, this exception is thrown:

org.glassfish.jersey.message.internal.HeaderValueException: Too many "Content-Type" header values: "[application/json; charset=utf-8, application/json]"

I use:

<dependency>
   <groupId>org.glassfish.jersey.core</groupId>
   <artifactId>jersey-client</artifactId>
   <version>2.25.1</version>
</dependency>

You will get this error when the response has more than one Content-Type response header. What you can do id reset the header to just use one by using response.getHeaders().putSingle(). This will override the double headers and just leave you with one.

response.getHeaders().putSingle(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON);
return gson.fromJson(response.readEntity(String.class), typeOfT);
