This error has been discussed before. You can google the jCIFS archives
very easily with search parameters like:

  site:lists.samba.org/archive/jcifs writeParameterWordsWireFormat
NullPointerException

The JRE you're using doesn't support the Cp850 encoding but the NetBeans
one does because it's the JDK. Set jcifs.encoding to ASCII (or it might
be "US-ASCII", can't remember) like:

  jcifs.Config.setProperty("jcifs.encoding", "ASCII");

Note that this is not a bug but the UnsupportedEncoding exception being
caught and ignored is (thanks Chuck). That is on The List. Also, since
this should only occur when the client communicates with a server that
doesn't support Unicode (e.g. old Samba servers, Windows 98, etc) I
think
I should change the encoding used when computing the ASNI password hash
from ServerMessageBlock.OEM_ENCODING to "ASCII".
