In "JDK-1.2beta2-V", when ui is set to JLF, clicking on Tabs causes ArrayIndexOutOfBoundsException.

To reproduce, please run the following Test :
1) %java TestShow
2) Press the button at the bottom to switch UIs between motif and jlf.
3) When the UI is jlf, move the mouse to the tab and click.
4) java.lang.ArrayIndexOutOfBoundsException is thrown.
