    window-actor: Special-case shaped Java windows
    
    OpenJDK wrongly assumes that shaping a window implies no shadows.
    They got lucky until commit b975676c changed the fallback case,
    but now their compliance tests are broken. Make them happy again
    by special-casing shaped Java windows.
