The CR 6383434 was closed as duplicate by mistake.

Look at the sample below:

import java.awt.*;

public class Test extends Frame {
    public Test() {
        setMinimumSize(new Dimension(400, 400));
        setMaximumSize(new Dimension(400, 400));
        setSize(400, 400);
        setVisible(true);
    }

    public static void main(String[] args) {
        new Test();
    }
}

When I run the code above I cannot decrease the size of the Frame less than [400,400]. But at the same time I *can* increase the size of the Frame. It seems we have some inconsistency: setMinimumSize does work whereas setMaximumSize doesn't work.

The test is running on jdk6 b69.
