    merge revision(s) 63698: [Backport #14856]
    
    lib/drb/extservm.rb (service): do not return `false'
    
    invoke_service_command may set entries in @servers to `false',
    making it incompatible with the intended use of the
    safe navigation operator.
    
    This caused occasional DRb test failures, but they were hidden
    with automatic retry.

    Fixes: r53111 ("use safe navigation operator")
