Issue description

I am working on my integration with PayPal Marketspace and I am using the Payment/Order V2 SDKs which references paypalhttp_java SDK. I noticed that the Seller Onboarding process has not been implemented so I had to build it my self. I created the following class:

`
@model
public class PartnerReferralRequestBody {

@SerializedName("tracking_id")
private String trackingId;

@SerializedName("email")
private String email;

@SerializedName("operations")
private List<Map<String, Object>> operations;

@SerializedName("products")
private List<String> products;

public PartnerReferralRequestBody() {
}

public PartnerReferralRequestBody(String hostId, String email) {
	this.trackingId = hostId;
	this.email = email;

	// Initialize the products
	this.products = new ArrayList<String>();
	this.products.add("EXPRESS_CHECKOUT");

	// Initialize the operations
	this.operations = new ArrayList<Map<String,Object>>();
	Map<String,Object> operation = new HashMap<String,Object>();
		operation.put("operation", "API_INTEGRATION");
		Map<String,Object> preference = new HashMap<String,Object>();
			Map<String,Object> integration = new HashMap<String,Object>();
				integration.put("integration_method", "PAYPAL");
				integration.put("integration_type", "THIRD_PARTY");
				Map<String,Object> details = new HashMap<String,Object>();
					ArrayList<String> features = new ArrayList<String>();
					features.add("PAYMENT");
					features.add("REFUND");
					details.put("features", features);
				integration.put("third_party_details", details);
			preference.put("rest_api_integration", integration);
		operation.put("api_integration_preference", preference);
	this.operations.add(operation);
}

public String getTrackingId() {
	return trackingId;
}

public void setTrackingId(String trackingId) {
	this.trackingId = trackingId;
}

public String getEmail() {
	return email;
}

public void setEmail(String email) {
	this.email = email;
}

public List<Map<String, Object>> getOperations() {
	return operations;
}

public void setOperations(List<Map<String, Object>> operations) {
	this.operations = operations;
}

public List<String> getProducts() {
	return products;
}

public void setProducts(List<String> products) {
	this.products = products;
}

}
`
and I got the following warning when I tried to make the following call:

PartnerReferralRequestBody requestBody = new PartnerReferralRequestBody(hostId, email); BaseHttpClient<PartnerReferralResponse> request= new BaseHttpClient<PartnerReferralResponse>("/v2/customer/partner-referrals", "POST", PartnerReferralResponse.class); request.requestBody(requestBody); HttpResponse<PartnerReferralResponse> response = paypalClient.execute(request);

Is this going to be a problem with any Bean implementing Serializable ?
