+/**
+ * EapSilentException represents a category of EAP errors that should be silently discarded by
+ * authenticators and peers.
+ *
+ * <p>EapSilentException is so-named due to its role in the EAP standard. RFC 3748 requires that
+ * several error cases be "silently discarded". In these cases, no EAP-Response message will be sent
+ * to the Authenticator. However, when thrown SilentExceptions will still signal an EAP failure to
+ * the IKE library calling it, resulting in an Authentication failure.
+ *
+ * Each type of silent error should implement its own subclass.
