Specification for public Dimension minimumLayoutSize(Container parent):
"Determines the minimum size of the container argument using this grid 
layout. The minimum width of a grid layout is the largest minimum width 
of any of the widths in the container times the number of columns, plus 
the horizontal padding times the number of columns plus one, plus the 
left and right insets of the target container. The minimum height of a 
grid layout is the largest minimum height of any of the heights in the 
container times the number of rows, plus the vertical padding times 
the number of rows plus one, plus the top and bottom insets of the 
target container".

Sample code:
====================== minimumLS.java ===============================
import java.awt.*;

public class minimumLS {

    public static void main(String argv[]) {
        int rows = 1; int cols = 2; 

        int hgap = 2; int vgap = 3;

        GridLayout gl = new GridLayout(rows, cols, hgap, vgap);
  
        Container parent = new Container();
        parent.setLayout(gl);
        parent.setSize(100, 200);

        Insets insets = parent.getInsets();
        System.out.println("Insets left " + insets.left + " right " +
                           insets.right + " top " + insets.top + 
                           " bottom " + insets.bottom);

        Component comp = new Component(){};
        comp.setSize(13, 24);

        parent.add(comp, "comp");
        System.out.println("comp min size " + comp.getMinimumSize());

        Component comp2 = new Component(){};
        comp2.setSize(19, 11);

        parent.add(comp2, "comp2");
        System.out.println("comp2 min size " + comp2.getMinimumSize());

        Dimension dim = gl.minimumLayoutSize(parent);
        System.out.println("minimum layout size " + dim);
    }

==========================================================================
So first was created GridLayout with 1 row and 2 columns. Its hgap was 
set to 2 and vgap was set to 3. Then created parent container. Then two
components were added to container. Sizes of components are (13, 24) and 
(19, 11).

Minimum layout size returned by gl.minimumLayoutSize(parent):
[width=40,height=24], it is not equal one according specification.

Minimum layout size according specification is 
width : max(13, 19) * 2 + 2 * (2+1) + 0 + 0 = 38 + 6 = 44
height : max(24, 11) * 1 + 3 * (1+1) + 0 + 0 = 24 + 6 = 30
