Hallo!
We are use the edtftpj-pro 3.9.0 and get following exception by executing of FTPClient.dirDetails(String) of the same FTPClient object and same path by second time:
com.enterprisedt.net.ftp.FTPException: 521 internal error

The first execution of FTPClient.dirDetails(String) works correctly. There are no delay between both requests.
We are using FileZilla Server version 0.9.41 beta
