[rpwils]

When a swagger json file has an empty set for Authorization the cod is throwing an ClassCastException
org.glassfish.json.JsonArrayBuilderImpl$JsonArrayImpl cannot be cast to javax.json.JsonObject

This is within SwaggerReaderImpl.

if(child1 != null) {
this.readAuthorizations(resourceListing, child1);
