error with jscrollpane when the window is resized Java swing

Question

I have a JPanel "loginPanel" which has a gridBaglayout as a layout, inside of this i have a jScrollPane "jScrollPane3" which have another jPanel "jPanel3" inside..

loginPanel = new javax.swing.JPanel();
loginPanel.setLayout(new java.awt.GridBagLayout());

jPanel3 = new javax.swing.JPanel();
jPanel3.setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());

jScrollPane3 = new javax.swing.JScrollPane();
jScrollPane3.setViewportView(jPanel3);

The reason why i am using gridBagLayout is because i want to center the jPanel3 at the center of the screen, and if i use that layout i can make it...

So, my problem comes when i resize the window...

maximized window (Without the problem):

resized window (This is the problem):

What could be the reason of this problem?

If i remove the jScrollPane from the jPanel3 the problem is solved, but i have to use it...

What can i do to solve this?

Thank you!
