For reasons unknown, it does not happen on Mathematica 5.0:

In[1]:= D[{x[1],x[2],x[3]},{{y[1],y[2],y[3]}},NonConstants->{x[1],x[2],x[3]}]
D::dvar: Multiple derivative specifier {{y[1], y[2], y[3]}}
does not have the form {variable, n} where n is a nonnegative machine
integer.
D::dvar: Multiple derivative specifier {{y[1], y[2], y[3]}}
does not have the form {variable, n} where n is a nonnegative machine
integer.
D::dvar: Multiple derivative specifier {{y[1], y[2], y[3]}}

General::stop: Further output of D::dvar
will be suppressed during this calculation.
