The output from version 4.6.6 is right. This file is the so-called netCDF-4
file, an HDF5 file that follows the netCDF-4 data model. You can use either
ncdump (from C) or HDFView/h5dump to check the values. I think this is related
to the fix of signed int representation in Java.

Subject: [netcdf-java] Difference between netcdfJava 4.6.5 and 4.6.6
Using the file downloaded a week ago from
http://data.nodc.noaa.gov/thredds/catalog/testdata/wod_ragged/05052016/catalog.html?dataset=testdata/wod_ragged/05052016/ind199105_ctd.nc
(and hopefully unchanged since),
if I use this Java code to dump the values of 3 scalar variables
StringWriter sw = new StringWriter();
NCdumpW.print(String2.unitTestDataDir +
"nccf/ncei/ind199105_ctd.nc<http://ind199105_ctd.nc>",
sw, false, false, false, false, "crs;WODf;WODfd", //;-separated
null /*cancel*/);
System.out.println(sw.toString());
with netcdfAll-4.6.5.jar, I get:
...
data:
crs =0
WODf =0
WODfd =0
with netcdfAll-4.6.6.jar, I get:
...
data:
crs =-2147483647
WODf =-32767
WODfd =-32767
I suspect that the 4.6.5 results are correct, but I'm not certain.
If so, then it is a bug in 4.6.6.
If not, then please let me know.
Or maybe I'm doing something wrong.
Can you please investigate?
Thank you.
If I should report this some other place/way, please let me know.
