loadResourceFileJson

public static com.fasterxml.jackson.databind.JsonNode loadResourceFileJson(String fileName)
                                                                    throws IOException

Loads a classpath resource as JSON. The resource is read through an InputStream so it resolves correctly whether it is a loose file on disk (e.g. running from an IDE) or packed inside a jar (where the URL is a jar:file:...!/... entry that cannot be turned into a Path).

Parameters:

fileName - the classpath-relative resource name (e.g. "json/apiParams_Core.json")

Returns:

the parsed JSON tree; never null

Throws:

FileNotFoundException - if no such resource exists on the classpath - a missing resource fails fast with the resource name rather than surfacing later as an opaque NPE during client bootstrap

IOException - if the resource exists but cannot be read or parsed
