      Description

      An InvalidToken exception is thrown for expired or cancelled tokens. An InvalidToken not wrapped in a RetriableException must be considered fatal by the retry proxies or clients will spam the service with failed connections. Depending on the context, a service may be degraded when spammed with thousands of connection failures.
