 * @param requestContext The {@link RequestContext} when this invocation is originally scheduled.
 *                       This must be the same object as {@link #requestContext} for synchronous
 *                       invocations, but for asynchronous invocations, it needs to be a snapshot
 *                       captured at the point of invocation, to correctly satisfy the spec requirement.
 * @param receiver       Receives the {@link ResponseContext}. Since the spec requires
 *                       that the asynchronous invocations must not update response context,
 *                       depending on the mode of invocation they have to go to different places.
 *                       So we take a setter that abstracts that away.
