      • clearReflectionCache

        public GraphQLUnusualConfiguration.PropertyDataFetcherConfig clearReflectionCache()
        PropertyDataFetcher caches the methods and fields that map from a class to a property for runtime performance reasons as well as negative misses.

        However during development you might be using an assistance tool like JRebel to allow you to tweak your code base and this caching may interfere with this. So you can call this method to clear the cache. A JRebel plugin could be developed to do just that.
