error about directoryList

FileTransferClient ftpClient = getNewFtpConn();
FTPFile[] ftpFiles = ftpClient.directoryList(remoteFileNameReg);
for(FTPFile ftpfile:ftpFiles)
System.out.println(ftpfile.getName());

it works. but one day, the name all are empty。why?

change to :

remoteFiles = ftpClient.directoryNameList();

it works.
