JList horizontal resize causes vertical shrink

I have a jList in a ScrollPane and it behaves weird when I am resizing my frame. Normally it is like this: Before And after I grow the table on the left horizontally, my jList becomes like this: After

I am posting some code of the gui which might be helpful:

    scrlInterfaceList.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED);
    scrlInterfaceList.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);

    //---- list1 ----
    lstInterfaces.setBorder(BorderFactory.createTitledBorder(LFwPolicyMaker.messages.getString("IpMacMatcher.MatchTab.controlPanel.interfaces.title")));
    lstInterfaces.setPreferredSize(null);
    lstInterfaces.setMaximumSize(new Dimension(55, 90));
    lstInterfaces.setMinimumSize(new Dimension(55, 90));

    lstInterfaces.setLayoutOrientation(JList.VERTICAL);
    lstInterfaces.setModel(new AbstractListModel() {

        String[] strings = getInterfaces();

        public int getSize() {
            return strings.length;
        }

        public Object getElementAt(int i) {
            return strings[i];
        }
    });
    scrlInterfaceList.setViewportView(lstInterfaces);

    setSelectedInterfaces();

    add(scrlInterfaceList,new GridBagConstraints(0, 5, 1, 1, 0.0, 0.0,
                GridBagConstraints.CENTER, GridBagConstraints.BOTH,
                new Insets(0, 0, 0, 0), 0, 0));

What might be the problem? I want the jList to continue shrinking horizontally, like the combobox, buttons above

Try setting the weighty value of the GridBagConstraints to 1.0 for the scrollpane
