Apache FTPSCleint.listFiles() returns empty array

Question

I'm trying to get files from ftp server with no luck. commons-net version 3.5

            FTPSClient ftpClient = new FTPSClient();
            ftpClient.connect("xxx.com", 21);
            ftpClient.enterLocalPassiveMode();
            ftpClient.login("login", "password");
            ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
            FTPClientConfig conf = new FTPClientConfig();
//            conf.setUnparseableEntries(true);
            conf.setServerTimeZoneId("UTC");
            ftpClient.configure(conf);
            ftpClient.execPBSZ(0);
            ftpClient.execPROT("P");
            return ftpClient;

Only after I uncommented conf.setUnparseableEntries(true) I got array of "something". isFile() method returns false so I can't use File's methods with it. All of them throws NullPointerException.

Any advise where is the problem and why Apache can't parse files?
