I believe the main issue here is that the code in the VisAD library
for HDF files has not been maintained by the original authors.  This
also is true of the netCDF adapter ("Plain").  Unfortunately, this
means that for files that use newer features in these formats, the
code no longer works.

I do not have any solutions, other than as Ghansham suggests, using
the "official" releases of the respective libraries and then building
your own VisAD Data objects...
