I have got a class containing inner class.
Whenever I open the source file I got endless
chain of exceptions regarding the inner class is
not found in index.

Annotation: Exception occurred in Request Processor
java.lang.IllegalStateException: Class not found

The inner class is rather simple:
     /*
     * Renderer for coloring lines by row status.
     */
    class StatusCellRenderer extends
BasicTableCellRenderer {

        public Component
getBasicTableCellRendererComponent(JTable table,
Object value, boolean isSelected,
                boolean hasFocus, int row, int
column) {
            if (getModel() instanceof
UWriteTableModel) {
                UWriteTableModel model =
(UWriteTableModel) getModel();
                Color c = getBackground();
                if (model.getRowCount() == row + 1
                        || ((WriteRow)
model.getRow(row)).getRowStatus() ==
RowStatus.NEW_ROW) {
                    c = new Color(c.getRed(),
c.getGreen(), c.getBlue() - 64);
                }
                else if (((WriteRow)
model.getRow(row)).getRowStatus() ==
RowStatus.UPDATED_ROW) {
                    c = new Color(c.getRed(),
c.getGreen() - 32, c.getBlue() - 32);
                }
                setBackground(c);
            }

            return
super.getBasicTableCellRendererComponent(table,
value, isSelected, hasFocus, row, column);
        }
    }
