>                 URL: https://issues.apache.org/jira/browse/FTPSERVER-302
>             Project: FtpServer
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 1.0.0
>            Reporter: Gusti Benawi
>
> A passive port is requested by calling the method DataConnectionConfiguration.requestPassivePort()
> The search of a free port is done by PassivePorts.reserveNextPort()
> The "free" port returned is based on an internal boolean flag, which determines whether a port is free or not. 
> This is bad since the port returned could be actually being used by another application. The port will still be returned, and an exception will be thrown since it will fail to create the data socket.
