But really, it's ALL, it's in the Java sources

A DESCRIPTION OF THE PROBLEM :
A quick perusal of the SwingSet2 and the source for DefaultTableCellRenderer shows that there is no attempt to paint the condition of "selected, but not focused."

Technically its not really showing Focus, but another concept. Let's call it "active selection". It is not separate from Focus, however, and can easily be shown in Java-land.

Visually, as a result in Java when two tables are visible and have a selected item at the same time, it appears as if they are both focused. (Not in the outline border sense, but in the active selection sense.).

As a note, eclipse/SWT does this correctly.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
In SwingSet2, go to the Table tab, select a row, then change your focus out of the table to a combobox, say. The row/column/cell will appear as if it still has focus and selection. (It really has selection, but not the focus).

This can be seen in Windows Explorer by turning on the Folders tree, selecting a directory, and then in the files part, selecting a file. The observant will note that the directory containing the currently displayed file has a grey background, and the current selection, with focus, has a blue background.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The row will appear blue, but another component will have focus.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
public Component getTableCellRendererComponent(JTable table, Object value,
                          boolean isSelected, boolean hasFocus, int row, int column) {

if (isSelected && !hasFocus) {
   // set the inactive selection colours
}
if (isSelected && hasFocus) {
super.setForeground(table.getSelectionForeground());
super.setBackground(table.getSelectionBackground());
}
else {
super.setForeground((unselectedForeground != null) ? unselectedForeground
: table.getForeground());
super.setBackground((unselectedBackground != null) ? unselectedBackground
: table.getBackground());
}

setFont(table.getFont());

if (hasFocus) {
setBorder( UIManager.getBorder("Table.focusCellHighlightBorder") );
if (table.isCellEditable(row, column)) {
super.setForeground( UIManager.getColor("Table.focusCellForeground") );
super.setBackground( UIManager.getColor("Table.focusCellBackground") );
}
} else {
setBorder(noFocusBorder);
}

        setValue(value);

return this;
    }
