I'm all in favor of upgrading to commons-net if it can fix some issues.
Do they have any time frame for a release ?

Gert Vanthienen commented on SM-915:
------------------------------------
On the commons mailing list, Rory Winston suggested to upgrade to
commons-net-2.0 RC, because it contains fixes for various threading
issues. It is available at
http://people.apache.org/~rwinston/commons-net-2.0/commons-net-ftp-2.0.0-SNAPSHOT.jar
However, it requires JDK5/6 and it is not a simple replacement for the
current commons-net-1.4.x.jar (API changes).
