Re: [netcdf-java] Reading HDF5 files with OPERA radar data by SMHI

Hi eleanora:

it appears that you have a special IOSP loaded at runtime:

org.ninjoworkstation.server.hdf5.Hdf5FileReader

my tests show that the default HDF5 reader is working correctly.

see

http://www.unidata.ucar.edu/software/netcdf-java/reference/RuntimeLoading.html

for how runtime loading works.
