We received several thousand requests for .nc files that don't actually exist in our system.

Instead of receiving an html based 404 result, the gateway was generating a 500 internal server error.

Here is the exception text:
javax.servlet.ServletException: Could not resolve view with name 'common/error/object-not-found' in servlet with name 'gateway'

What was happening, is that spring, was resolving the .nc extension to the application/x-netcdf mime-type. Then spring was trying to find a view resolver for that mime-type, but, of course, we do not have a view resolver for that mime-type and therefore, the exception above was being created.

Acceptance Criteria:

For now, we are planning on extending the ContentNegotiatingViewResolver and to use the text/html view resolver as a default if we cannot find any other view resolvers.
