Hi , 

I was using old version of edtFTPj/PRO which was working fine. Recently client side server installed new patch for "sun solaris" after that my old jar was not working.I installed latest version which is available in website. It gives me below error when HostValidationEnabled(true) 

com.enterprisedt.net.ftp.ssh.SSHFTPKeyException: The host signature is invalid or the host key was not accepted!

If i disable host validation then code working fine.
