Why is KeyManagerUtils.loadStore private?

Question

I am working on a project and I have implemented something like this...

    public static KeyStore getInstance(String storeType, Resource location, String password) throws IOException,
        KeyStoreException,
        CertificateException,
        NoSuchAlgorithmException {
        KeyStore keyStore = KeyStore.getInstance((storeType != null ? storeType : DEFAULT_STORE_TYPE));
        try (FileInputStream fileInputStream = new FileInputStream(location.getFile())) {
            keyStore.load(fileInputStream, password.toCharArray());
        }
        return keyStore;
    }

I noticed that common-net has something similar in loadStore but it is private. Why is that? Is it something about the way the manager is constructed or something?
