When a JOptionPane is initilized and displyed from an application. The following
warning message is displayed on the command prompt.
"JVM warning-increase BUFLEN in ostream.cpp -- output truncated"

This bug affects all windows platforms(Win95, Win98, Win NT, Win 2000) under English/Arabic/Hebrew locales.

To reproduce bug:

1- Compile and run the following code
2- From the menu choose a choice and click on it.
3- Note that a JOptionPane is displaed
4- Note that a wrning message is diplayed on the command prompt.
5- Repeat previous steps
6- Note that each time a JOptionPane is displayed, the warning message is displayed
