When loading GRIB2 files downloaded from the National Hurricane Center forcast data ( https://ftp.nhc.ncep.noaa.gov/wsp/ ), I get a NPE from within the NetCDF parser:

Caused by: java.lang.NullPointerException

This most often happens when first loading the layer into GeoServer, but I’ve also encountered it when trying to view any time dimension other then the first.
