it's obvious the Auto Smooth inherits its enabled or disabled state from the last Object selected before Joining, but should not discard the Mark Sharp information.

Sharp edges are not lost, they are just no more visible by default because the relevant draw option (Mesh Display panel in properties (N)) is disabled. Thanks for the report, but no bug at all here.
