JXTreeTable Substance L&F paint issues

Question

The first column of JXTreeTable is not painted on hover when using the substance look and feel. The problem persists when that same column is dragged to another position as well.

Also the border is not painted as well. Is there any workaround for this?

I am using substance business l&f. I included substance swingx plugin as well.

Environment : Windows 7, JDK 1.6, SwingX 1.6.3, Substance 7.1

public class SwingXExample extends JFrame {
private JTabbedPane tabs = new JTabbedPane();
private JXTreeTable treeTable;
public SwingXExample() {
    JPanel treeTablePanel = new JPanel(new BorderLayout());
    treeTable = new JXTreeTable(new MyTreeTableModel());
    treeTablePanel.add(new JScrollPane(treeTable));
    tabs.addTab("JXTreeTable", treeTablePanel);
    add(tabs);
}

public static void main(String[] args) {
    SwingUtilities.invokeLater(new Runnable() {
        @Override
        public void run() {
            try {
                UIManager.setLookAndFeel(new SubstanceBusinessBlueSteelLookAndFeel());
            } catch (UnsupportedLookAndFeelException e) {
                e.printStackTrace();
            }
            SwingXExample frame = new SwingXExample();
            frame.setSize(400, 300);
            frame.setVisible(true);
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        }
    });
}
}

Tree Table Model

public class MyTreeTableModel extends AbstractTreeTableModel {
    private MyTreeNode myroot;

public MyTreeTableModel() {
    myroot = new MyTreeNode("root", "Root of the tree");
    myroot.getChildren().add(
            new MyTreeNode("Empty Child 1", "This is an empty child"));

    MyTreeNode subtree = new MyTreeNode("Sub Tree",
            "This is a subtree (it has children)");
    subtree.getChildren().add(
            new MyTreeNode("EmptyChild 1, 1",
                    "This is an empty child of a subtree"));
    subtree.getChildren().add(
            new MyTreeNode("EmptyChild 1, 2",
                    "This is an empty child of a subtree"));
    myroot.getChildren().add(subtree);

    myroot.getChildren().add(
            new MyTreeNode("Empty Child 2", "This is an empty child"));
}

@Override
public int getColumnCount() {
    return 3;

@Override
public String getColumnName(int column) {
    switch (column) {
    case 0:
        return "Name";

    case 2:
        return "Number Of Children";
    default:
        return "Unknown";
    }
}

@Override
public Object getValueAt(Object node, int column) {
    // System.out.println( "getValueAt: " + node + ", " + column );
    MyTreeNode treenode = (MyTreeNode) node;
    switch (column) {
    case 0:
        return treenode.getName();
    case 1:
        return treenode.getDescription();
    case 2:
        return treenode.getChildren().size();
    default:
        return "Unknown";
    }
}

            return i;
        }
    }
    return 0;
}

public boolean isLeaf(Object node) {
    MyTreeNode treenode = (MyTreeNode) node;
    if (treenode.getChildren().size() > 0) {
        return false;
    }
    return true;
}

@Override

    return myroot;
