This is either a documentation bug, or some sort of logging bug, but it did cause me to chase ghosts for a few hours.

According to https://docs.geoserver.org/maintain/en/user/extensions/netcdf-out/nc4.html#geoserver-startup-checks, there is supposed to be an indication in a log (which?!) that the loading of the native netcdf4 library was successful or failed. As far as I can tell, neither message appears in any log that I could find as of v2.17.2 (the only version I have tried). Spent a bunch of time trying to figure out what went wrong before finally deciding to actually try a WCS call with application/x-netcdf4 as an output format, and it worked.

Possibly related, the WCS Capabilities document also doesn’t advertise that it supports application/x-netcdf4, only application/x-netcdf, which corresponds to NetCDF-3. Maybe that is tied in with the lack of any logging message, I don’t know…
