21 * This exception is used for most types of failures that occur during server interactions.
22 *
23 * Data passed through this exception should be considered non-localized.  Any strings should
24 * either be internal-only (for debugging) or server-generated.
25 *
26 * TO DO: Does it make sense to further collapse AuthenticationFailedException and
27 * CertificateValidationException and any others into this?
