Spring Layout not resizing correctly

Question

I am new to the spring layout in Java GUI building, but it seemed that using spring layout was the only way to go if I wanted to layout my GUI the way I wanted.

The problem I am having, is that one of the panels of my GUI expands about a pixel or 2 when I set resizable to false on my JFrame. But when I set resizeable to true, everything lines up perfectly the way I want. I know 1 or 2 pixels isn't off by much, but it's enough to make my GUI look weird because some of the text boxes are stretched 1 or 2 pixels larger then the others. Here is the code for my spring layout:

    pnlTop.setLayout(layout);

    lblClosetLoc.setText("Closet location:");
    lblPhone1.setText("Phone 1:");
    lblJackPaired.setText("Jack paired:");
    lblPhone2.setText("Phone 2:");
    lblCubicle.setText("Cubicle:");
    lblJackType.setText("Jack type:");
    lblName.setText("Name:");
    lblPhoneJack1.setText("Phone jack 1:");
    lblPhoneJack2.setText("Phone jack 2:");
    lblDataJack1.setText("Data jack 1:");
    lblDataJack2.setText("Data jack 2:");
    lblComments.setText("Comments:");

    txtClosetLoc.setEditable(false);
    txtClosetLoc.setText("");
    txtPhone1.setEditable(false);
    txtPhone1.setText("");
    txtJackPaired.setEditable(false);
    txtJackPaired.setText("");
    txtPhone2.setEditable(false);
    txtPhone2.setText("");
    txtCubicle.setEditable(false);
    txtCubicle.setText("");
    txtJackType.setEditable(false);
    txtJackType.setText("");
    txtFname.setEditable(false);
    txtFname.setText("");
    txtLname.setEditable(false);
    txtLname.setText("");
    txtPhoneJack1.setEditable(false);
    txtPhoneJack1.setText("");
    txtPhoneJack2.setEditable(false);
    txtPhoneJack2.setText("");
    txtDataJack1.setEditable(false);
    txtDataJack1.setText("");
    txtDataJack2.setEditable(false);
    txtDataJack2.setText("");

    txtComments.setText("");

yes, the very last thing after i attach the panel to the content pane reads this.setResizable(false); this.pack(); — Caveman42, Oct 24 '12 at 17:50
Post a [SSCCE](http://sscce.org) to demonstrate the problem something else could be going wrong — David Kroukamp, Oct 24 '12 at 17:52
After creating the SSCCE it seems to work fine, but the actual program is still stretching by 1 or 2 pixels, with the same things running as the new text program. I will still post the SSCCE i created in a moment. Also i just noticed that if i run both programs side by side, the original is stretched a little — Caveman42, Oct 24 '12 at 18:09
Well then something in your old code is wrong. use your SSCCE as the foundation and add functionality from older version to the new one until you have all functions working (this way you will see which function you add that is giving problems) — David Kroukamp, Oct 24 '12 at 18:13
