[netCDFJava #QVA-393299]: Problem reading HDF4 and HDF5 files

Hi Antonio:

In 4.2 we tried to allow blanks in the group names. this caused too much 
trouble, so we replace them with "_", i guess starting in 4.3. 
So the correct name is Data_Fields not Data Fields
We try to stay backwards compatible, but sometimes we cant, sorry for the 

The correct thing to do is to get a listing of variables in the file, to see 
what the valid variable names are.

> The follwing code works fine for JavaNetCDF 4.2 but variable=null for

> String path = groupInFile + SUBDATASETS_GROUP_DELIMITER +
> nameInGroup; // == "/HDFEOS/GRIDS/ColumnAmountNO2/Data
> Fields/ColumnAmountNO2TropCloudScreened"
> Variable findVariable = file.findVariable(path); // returns "null"
> while in JavaNetCDF version 4.2 it is OK
> where "file" is "NetcdfFile"
> The HDF5 file used in this code can be found here:
