[netCDFJava #AYO-259890]: Malformed URL and .dds appended to URL

Hi Jo Ellen:

in openNetcdfGridDataset, the URL

 
file:/C:/VERDI_test/VERDI_1.5.1_test03092015/data/model/CCTM46_P16.baseO2a.36k.O3MAX

is converted to

 /C:/VERDI_test/VERDI_1.5.1_test03092015/data/model/CCTM46_P16.baseO2a.36k.O3MAX

which passes 

  NetcdfFile.open()

but fails on 

 GridDataset.open(urlString)


I would suggest that you remove the part that strips ofd "file" but leaves the 
leading "/". Basically 
dont use 

  urlString = new URI(urlString).getPath();

I will also check if we should be accepting the leading "/", but that will take 
a while.

        private GridDataset openNetcdfGridDataset(URL url) throws 
URISyntaxException, IOException {
                Logger.debug("in NetcdfDatasetFactory.openNetcdfGridDataset, 
url = " + url);
                String urlString = url.toExternalForm();
                Logger.debug("when converted .toExternalForm(), urlString = " + 
urlString);
                
                if (url.getProtocol().equals("file")) {
                        Logger.debug("url.getProtocol().equals('file') so ready 
to get updated urlString");
                        urlString = new URI(urlString).getPath();
                        Logger.debug("updated urlString = " + urlString);
                }
                
                validNetcdfFile( urlString);
                Logger.debug("back from validNetcdfFile");

                // return GridDataset.open(urlString); // NetCDF ENHANCE
                Logger.debug("ready to call GridDataset.open for urlString = " 
+ urlString);
                GridDataset gridDataset = GridDataset.open(urlString);
                
//              if ( 1 == 2 )
//                      printGridDatasetInfo( gridDataset);

                return gridDataset;
        }
