java swing minimizing and expanding a jPanel

Question

This program is an experiment to make the jPanel move position and size then back again using swiping (touch screen).

Here is a picture of a frame: before anything, after minimizing and then after maximizing. The first and third one should be identical but are not.

With the code that I am using I can see no reason for the change in text location, and it is only text nothing other.

Edit: just found out the if i minimize the actual program and maximize it the panel is corrected so it could be a drawing problem (so i tried repaint()) and it didn't make a difference. any idea's what is causing this?

My working code example:

import java.awt.Color;
import java.awt.Component;
import java.awt.Dimension;
import java.awt.Point;
import java.awt.Toolkit;
import java.util.HashMap;
import java.util.Map;
import javax.swing.JPanel;

public class TestExample extends javax.swing.JFrame {

    public TestExample() {
        initComponents();
    }
    @SuppressWarnings("unchecked")                       
    private void initComponents() {

        jPanel1 = new javax.swing.JPanel();
        jLabel3 = new javax.swing.JLabel();
        jButton1 = new javax.swing.JButton();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        setResizable(false);
        getContentPane().setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());

        jPanel1.setBorder(javax.swing.BorderFactory.createLineBorder(new java.awt.Color(0, 0, 0)));
        jPanel1.setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());

        jLabel3.setText("A Text Line");
        jPanel1.add(jLabel3, new org.netbeans.lib.awtextra.AbsoluteConstraints(20, 0, -1, -1));

        getContentPane().add(jPanel1, new org.netbeans.lib.awtextra.AbsoluteConstraints(120, 20, 90, 50));

        jButton1.setText("Test");
        jButton1.addMouseListener(new java.awt.event.MouseAdapter() {
            public void mouseClicked(java.awt.event.MouseEvent evt) {
                jButton1MouseClicked(evt);
            }
        });
        getContentPane().add(jButton1, new org.netbeans.lib.awtextra.AbsoluteConstraints(20, 20, -1, -1));

        pack();
    }                    

    private void jButton1MouseClicked(java.awt.event.MouseEvent evt) {                                      
   JPanel p = jPanel1;
    int div = 5;
    if(small == true) {//SWIPE LEFT

                c.setSize(dim);
                c.setLocation(location.get(c));
            }
        p.setLocation(ploc);
    } else if( small == false) {//SWIPE RIGHT
        small = true; 
        ploc = p.getLocation();
        dim = p.getSize();
        for(Component c : p.getComponents()) {
            location.put(c, c.getLocation());
        }
        for(int i = p.getWidth()/div;i<p.getWidth();i++) {//minimize X coordinate
            Dimension d = new Dimension(p.getWidth()-i, p.getHeight());
            p.setSize(d);
            for(Component c : p.getComponents()) {

            }
        }
