Apaches FTPSClientを使用してFTPに接続しようとしていますが、次のエラーが発生し続けます。

06-15 09：15：14.749：W / System.err（29451）：java.io.IOException：SSLコンテキストを初期化できませんでした

これは次のコードで発生し、エラーは2行目（接続）に発生します。

ftpsClient = new FTPSClient("SSL");
ftpsClient.connect(host);
int reply = ftpsClient.getReplyCode();
if(!FTPReply.isPositiveCompletion(reply)) {
    ftpsClient.disconnect();
}
ftpsClient.login(user, password + nl);
ftpsClient.setFileType(FTP.BINARY_FILE_TYPE);
ftpsClient.enterLocalPassiveMode();

私が間違っているかもしれないことの提案はありますか？

何らかの理由でデフォルトKeyManagerを作成できないため、SSLコンテキストの初期化が失敗します。デフォルトのものを手動でインストールしてみてください。何かのようなもの：

KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
kmf.init(null, null);
KeyManager km = kmf.getKeyManagers()[0];

ftpsClient = new FTPSClient("SSL");
ftpsClient.setKeyManager(km);
