The Fix of Chart-13 might not be the actual cause of the bug.

[jmueducn]

patch fixed the bug by adding a Math.max function to make sure the Range is not negative.

However, the actual reason of the bug is w[2] > constraint.getWidth(), which should not be the case.

if (this.leftBlock != null) {
            RectangleConstraint c3 = new RectangleConstraint(0.0,
                    new Range(0.0, constraint.getWidth()),
                    LengthConstraintType.RANGE, h[2], null,

            Size2D size = this.leftBlock.arrange(g2, c3);
            w[2] = size.width;
        }

It is because the arrange method in some Block class did not handle constraint correctly.
In Emptyblock.java:

    public Size2D arrange(Graphics2D g2, RectangleConstraint constraint) {
        return new Size2D(calculateTotalWidth(getWidth()), 
                calculateTotalHeight(getHeight()));
    }

In AbstractBlock.java, it handled it correctly:

public Size2D arrange(Graphics2D g2, RectangleConstraint constraint) {
        Size2D base = new Size2D(getWidth(), getHeight());
        return constraint.calculateConstrainedSize(base);
    }

However, in actual test, the method in emptybock class override it.
