Hello all,
I've the following netcdf file with a vlen_t type in one variable... When I
try to read with the following Java code I get the error that is showed
bellow. Anyone know when I can read a vlen_t variable?

types:

        ushort(*) vlen_t;

dimensions:
        acqtime = UNLIMITED ; 

variables:
        uint acqtime(acqtime) ;
                acqtime:long_name = "Acquisition time" ;
        (...)
        vlen_t levels(acqtime);
                levels:long_name = "Acquired values array" ;


data:
        acqtime = 1,2,3,4,5,6,7,8,9,10;
        levels={1,1,1,2,3,4,5,6,7,8},
                {2,2,2,3,4,5,6,7,8,9},
                {3,3,3,4,5,6,7,8,9,10},
                {4,4,4,5,6,7,8,9,10,11},
                {5,5,5,6,7,8,9,10,11,12},
                {6,6,6,7,8,9,10,11,12,13},
                {7,7,7,8,9,10,11,12,13,14},
                {8,8,8,9,10,11,12,13,14,15},
                {9,9,9,10,11,12,13,14,15,16},
                {10,10,10,11,12,13,14,15,16,17};
}


-------------------------------
           dataFile = NetcdfFile.open(filename, null);

           // Retrieve the variable named "data"
            Variable dataVar = dataFile.findVariable("levels");

            if (dataVar == null) {
                System.out.println("Cant find Variable data");
                return;
            }

            try {
                   Array data = dataVar.read();
               } catch (IOException ioe) {
                   System.out.println("trying to read " +  ioe);
               }
