java awt or Swing component missing or not shown

Question

i've been charged with a new software tool, and im trying to test it.

PROBLEM: I noticed a difference between mine GUI and the GUI of the tool run on the server: a component is missing! It is like if it's not shown, because i went in debug mode, and everything seems to be fine. this image shows the different:

as you can see, the "Shaft end Dia" component is missing between the others 2 components.

CODE: here is a code part. There are lots of items that get instantiate and added in the same way, but it doesn't apper on my pc (but they works well in others!!)

//PanelContainerClass
public class myInputPanel extends JPanel {
//myInputPanel fields
private JPanel myPanelMissing = null;
private JLabel jLabel_ofPanelMissing = null;

//myInputPanel is added to the mainFrame.
public myInputPanel() {
    super();
    initialize();
}

private void initialize() {
    //a GridBagConstraints is created for each panel i m going to add to myInputPanel
    GridBagConstraints gbc6 = new GridBagConstraints();
    gbc6.gridx = 6;
    gbc6.ipadx = 46;
    gbc6.fill = GridBagConstraints.BOTH;
    gbc6.insets = new Insets(0, 0, 0, 0);
    gbc6.ipady = 0;
    gbc6.gridy = 1;
    //in a similiar way others gbc are instantiate

    //a layout is given to myInputPanel
    GridBagLayout gridBagLayout = new GridBagLayout();
    gridBagLayout.columnWidths = new int[]{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 176, 0, 63, 0, 0, 0, 0, 0, 0, 0};
    this.setLayout(gridBagLayout);
    this.setSize(1185, 120);        
    this.setPreferredSize(new Dimension(1164, 143));
    this.setBorder(BorderFactory.createEtchedBorder(EtchedBorder.LOWERED));


    // add others panels to myInputPanel using this.add(getPanel_X(), gridBagConstraintsN);
    this.add(getmyPanelMissing(), gridBagConstraints6);
    // add others panels to myInputPanel using this.add(getPanel_Y(), gridBagConstraintsM);

}

private JPanel getmyPanelMissing() {
    if (myPanelMissing == null) {
        //in debug it get inside the if
        jLabel_ofPanelMissing = new JLabel();
        jLabel_ofPanelMissing.setHorizontalAlignment(SwingConstants.CENTER);            
        jLabel_ofPanelMissing.setText("<html><body>" +                  
                "<table cellspacing='0';cellpadding='0';> <tr> <td align='center'>Shaft end Dia</td> </tr> <tr> <td align='center'>[mm]</td> </tr></table>" +                           
                "</body></html>");
        GridLayout lay = new GridLayout();
        lay.setRows(1);
        myPanelMissing = new JPanel();
        myPanelMissing.setBorder(new SoftBevelBorder(SoftBevelBorder.RAISED));
        myPanelMissing.setLayout(lay);
        myPanelMissing.add(jLabel_ofPanelMissing, null);
    }
    return myPanelMissing;
}

}

What i tried to do is:

running it via my Eclipse: FAIL
running the jar via .bat file: FAIL (FAIL means it doesn't appear)
running the jar on the server via .bat file: WORKS
running the jar via eclipse on a colleague's computer by downloading the code via cvs: WORKS
running the jar via .bat on colleague's computer giving him my files: WORKS
running the jar via .bat on colleague's computer with files compiled by himself: WORKS
commenting the previous panelColumn on my code: WORKS!!!!

NOTE: 1) java version: 1.7.0.75 (either on mine pc either on my collegue pc) 2) OS: window 7 on Vbox (either me and collegue) 3) Eclipse Luna 4.x (same version again for both)

QUESTION: Has anyone had this kind of problems? Any idea about how to solve it?

Thank you all in advance!
