The Javadoc comment does say:
* Beware, for performace reasons the ordinate index is not
checked, if
* it's over dimensions you may not get an exception but a
meaningless
* value.
I didn't write this code, so I have no idea if the performance is really
that much of an issue. I wouldn't have thought so, but it needs testing
to be sure.

The implementation of the packedCoordinate sequence does not do any
dimension checking on the ordinate argument. Therefore if you say have a
2D coordinate sequence and request the 3 ordinate (z) then you will
actually be returned the value for the x value of the next coordinate.
The implementation to be safe should be something like.
public double getOrdinate(int index, int ordinate) {
if (ordinate > dimension) {
return Double.NaN;
} else {
return coords[index * dimension + ordinate];
}
}
