 * Generic Exception.
 * Please set the exception Id accordingly as this can be used to link client problems to log files/database.
 *
 * Please note that upon construction an exception Id will be generated using {@link java.util.UUID}.
 * This can be changed using the withExceptionId(String id) method.
 * Setting the correlation Id maybe useful when calling external services and to map local exceptions with external ones.
