Exceptions of this type are used when the error type is unknown. Harfang looks for an "Exception" instance or a String instance when catching errors. However, an error with a type not covered in the previous cases may be thrown. When the type is unknown, the framework wraps the error in a WrappedException.
Do not directly use this class. Use standard Exceptions instead. This is only used by the framework to wrap any unknown error types into an Exception.
