Java SE (Java Platform, Standard Edition)

I have a strange bug with every java app i run with the Java 7 VM. Every frame is limited to a maximum width of 1024 pixels. Doesn't matter if you try to resize it by code or dragging the border with the mouse pointer.

I have a Macbook with Mac OSX 10.7.5 (1280x800 resolution).

If i try to run the apps with Apple's Java 6 VM all works as expected.

Here is a POC:

import javax.swing.*;
import java.awt.*;


public class JDK7Bug {
    public static void main(String[] args) throws InterruptedException {
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
        frame.setSize(800, 400);
        Thread.sleep(100);
        System.out.println("frame.setSize(800, 400); " + frame.getSize());
        frame.setSize(1100, 400);
        Thread.sleep(100);
        System.out.println("frame.setSize(1100, 400); " + frame.getSize());
        frame.setSize(1000, 400);
        Thread.sleep(100);
        System.out.println("frame.setSize(1000, 400); "+frame.getSize());
        System.out.println("ScreenSize: "+Toolkit.getDefaultToolkit().getScreenSize());
    }
}

It outputs:

frame.setSize(800, 400); java.awt.Dimension[width=800,height=400]
frame.setSize(1100, 400); java.awt.Dimension[width=1024,height=400]
frame.setSize(1000, 400); java.awt.Dimension[width=1000,height=400]
ScreenSize: java.awt.Dimension[width=1280,height=800]
