type-inference-wip branch: objects are compared to 0 instead of null

Hi, method com.paypal.android.foundation.account.model.Contact.equals(Object)

    public boolean equals(java.lang.Object obj) {
        boolean z = true;
        if (this == obj) {
            return true;
        }
        if (obj != 0) { // <<<
            if (getClass() == obj.getClass()) {
                com.paypal.android.foundation.account.model.Contact contact = (com.paypal.android.foundation.account.model.Contact) obj;
                if (this.uniqueId != null) {
                    z = this.uniqueId.equals(contact.uniqueId);
                } else if (contact.uniqueId != null) {
                    z = false;
                }
                return z;
            }
        }
        return false;
    }

Hi, I've noticed the same thing in new codes, file com/paypal/android/foundation/p2p/operations/PayPalMeOperationsFactory.java

    public static com.paypal.android.foundation.core.operations.Operation<com.paypal.android.foundation.p2p.model.PayPalMeSuggestionsResult> newPayPalMeSuggestionsOperation(com.paypal.android.foundation.core.operations.ChallengePresenter challengePresenter, @android.support.annotation.Nullable java.lang.Object obj, int i) { // java.lang.Object obj is java.lang.String str in master branch
        com.paypal.android.foundation.core.CommonContracts.requireAny(challengePresenter);
        org.json.JSONObject jSONObject = new org.json.JSONObject();
        try {
            java.lang.String str = "preferred_id";
            if (obj == 0) { // compared with 0
                obj = org.json.JSONObject.NULL;
            }
            jSONObject.put(str, obj);
