Method javax.swing.JTabbedPane.setMnemonicAt(int index, int mnemonic) throws incorrect
exception when index is out of bounds.

The javadoc says:
-----------------------

public void setMnemonicAt(int index,
                          int mnemonic)
      ...
      Parameters:
            index - the tab index to which the mnemonic will be set
            mnemonic - the key code which represents the mnemonic
      Throws:
            IllegalArgumentException - if index is out of bounds
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
----------------------------------------

In fact, the method throws ArrayIndexOutOfBoundsException
instead IllegalArgumentException.
It needs to be fixed.

Here is an example:
---------------------------------------------
import javax.swing.JTabbedPane;

public class test {

  public static void main(String[] args) {
      JTabbedPane c = new JTabbedPane();
      for (int i = 0; i < 3; i++) {
          c.addTab("", null, new java.awt.Canvas());
      }
      // Should throw IAE
      try {
          c.setMnemonicAt(3, java.awt.event.KeyEvent.VK_A);
      } catch (IllegalArgumentException iae) {
          System.out.println("PASSED");
      }
  }

}
---------------------------------------------

Output:
------------------------
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 3 >= 3
        at java.util.Vector.elementAt(Vector.java:418)
        at javax.swing.JTabbedPane.setMnemonicAt(JTabbedPane.java:1380)
        at test.main(test.java:12)
