Well you'd better figure it out because 0.6.0 has a serious bug in it:

  Thu Feb 21 03:02:23 EST 2002
  jcifs-0.6.1 released
  If a file is retrived using the SmbFileInputStream class, the file's size
  is precisely a multiple of 4096 and the byte[] b and int len parameters
  used in a read() operation are both larger than 4096, the read( byte[]
  b ) and read( byte[] b, int off, int len ) methods will return -1. The <=
  condition in the middle of read( b, off, len ) has been changed to just <.

But maybe 0.6.1's SmbFileInputStream still has an issue. Note the file
size of files it chokes on if possible.
