JLabel text hidden behind another component in GridBagLayout

Question

Hi everyone
I have looked for an answer to this but come up short so here I am.
I am using GridBagLayout to position some Jlabels and a JScrollPane
I have a JLabel in gridx = 0 and gridy = 0 which spans 2 columns
under that in gridx = 0, gridy = 1 I have a JList inside a JScrollPane
it only spans the 1 column but fills the entire column.
next to this in gridx = 1, gridy = 1 I have a JLabel which should fill the rest of the row. It does this but the text is hidden behind the JScrollPane.
I have tried changing the fill to REMAINING but then the label does not fill the required area.
Any ideas why this is happening and how to fix it
my code is
contents = (JPanel) getContentPane();
tabbedPane = new JTabbedPane();
panel = new JPanel();
panel.setLayout(gridbag);
//left hand side
label = new JLabel("Video Database System",JLabel.CENTER);
gridConstraints.gridx = 0;
gridConstraints.gridy = 0;
gridConstraints.gridwidth = 2;
gridConstraints.weightx = panel.getWidth() * 0.3;
gridConstraints.weighty = 0.03;
gridConstraints.anchor = GridBagConstraints.NORTH;
gridConstraints.fill = GridBagConstraints.BOTH;
gridbag.setConstraints(label,gridConstraints);
label.setOpaque(true);
label.setBackground(Color.blue);
label.setFont(boldFont);
panel.add(label);
//scrolling list
list = new JList(FileAccess.titleDVD);
scrollPane = new JScrollPane(list);
gridConstraints.gridx = 0;
gridConstraints.gridy = 1;
gridConstraints.weightx = 0.3;
gridConstraints.weighty = 0.7;
gridConstraints.gridheight = 7;
gridConstraints.anchor = GridBagConstraints.WEST;
gridConstraints.fill = GridBagConstraints.VERTICAL;
gridbag.setConstraints(scrollPane,gridConstraints);
panel.add(scrollPane);
//labels in the right hand side, this is the label where the text becomes hidden
label = new JLabel("TITLE",JLabel.LEFT);
gridConstraints.gridx = 1;
gridConstraints.gridy = 1;
gridConstraints.weighty = 0.7;
gridConstraints.weightx = 0.9;
gridConstraints.anchor = GridBagConstraints.NORTH;
gridConstraints.fill = GridBagConstraints.HORIZONTAL;
gridbag.setConstraints(label,gridConstraints);
label.setOpaque(true);
label.setBackground(Color.yellow);
panel.add(label);
tabbedPane.add(panel,"Video Information");
Thanks
