This can be resolved by changing the renderer in DefaultCellRenderer;
protected static final FixedCellRenderer m_FixedRenderer = new FixedCellRenderer(STYLE_FLAT);

To include the INDICATION_FOCUS flag;
protected static final FixedCellRenderer m_FixedRenderer = new FixedCellRenderer(STYLE_FLAT | INDICATION_FOCUS);

I am not sure the proposed fix of changing 'focus' to 'clicked' would resolve this?
