I'm experiencing the same problem as Dennis.

Out of 100 file transfers 2 InputStream's were returned as null.
And, which was my original problem, on one occation the application hung. See
the Java thread below. 

Seems like the FTPClient.retrieveFileStream() call now and then returns a null
InputStream and occationally hangs...

I'm currently using version 1.3.0 so I'll try Dennis fix with the 1.4.0.

Regards,
 Anders M
