Reported on EC:

Compiling this code leads to a NPE. See stack trace below.

===== START SOURCE =====
import javax.swing.table.AbstractTableModel;
  public class MyTableModel extends AbstractTableModel {
    private String stuff = {
      {"A","B","C","D","E","F"},
      {"A","B","C","D","E","F"},
      {"A","B","C","D","E","F"}};
  public int getRowCount() {
    return stuff.length;
  }
  public int getColumnCount() {
    return stuff[0].length;
  }
  public Object getValueAt(int r, int c) {
    return stuff[r][c];
  }
}
===== END SOURCE =====

The problem has been reproduced using latest 2.0 JDT Core HEAD contents.
