      Description

      Swing-pre-1.0, jdk1.1.5.

      JTable throws exception : "java.lang.ArrayIndexOutOfBoundsException" when the table is empty.

      See below for a program desmontrating this bug.

      Removing the comments "//" at the beginning of the line "//
      rows.addElement(row);" solves the problem as the table is not anymore
      empty.
