NullPointerException at listFi les

Hi All,

We encountered the same problem as Dora reported.
https://lists.samba.org/archive/jcifs/2012-January/009856.html

Then we used JCIFS-1.3.18b.
http://jcifs.samba.org/jcifs-1.3.18b.jar

However this patch does not help us.
Any ideas?

<environment>
JCIFS : 1.3.18b
Network access : using DFS

<stacktrace>
Caused by: java.lang.NullPointerException
