In some cases the key value fetch fails, due to consul being down for a few seconds, or the connection failing, in which case this flag is set to false. If it is set to false, the getConfiguration() method keeps on throwing IllegalStateExceptions, bringing our entire application down.
I think the purpose of the initialized flag was to to prevent getConfiguration() being called before init() completed, and hence setting the flag here is not needed.
