In java.awt.GridBagLayout (v1.1 & v1.1.1) we have the
following:

public class GridBagLayout implements LayoutManager2,
                                      java.io.Serializable {
 
  protected static final int MAXGRIDSIZE = 512;
:
:
}


The maximum number of rows ( & columns ) is set by a constant
and cannot be changed. I have a scroll area and require more
than 512 widgets.

I can consistently get GridBagLayout to throw the following exception:

java.lang.ArrayIndexOutOfBoundsException
        at java.awt.GridBagLayout.GetLayoutInfo(Compiled Code)
        at java.awt.GridBagLayout.preferredLayoutSize(GridBagLayout.java:476)
        at java.awt.Container.preferredSize(Container.java:563)
        at java.awt.Container.getPreferredSize(Container.java:546)
        at javax.swing.JComponent.getPreferredSize(Compiled Code)
        at camcyber.repl.snmp.mrgo.QueryResultDialog.displayByRow(Compiled Code)
...

The problem appears to be associated with the number of rows in the layout. If there are fewer than about 512 rows, then I never get the exception. The exception always gets thrown if there are more than about 512 rows in the layout.
