A DESCRIPTION OF THE PROBLEM :
Below you will see the little program used to shown the problem with paintComponent(..).

If I run this program with "jre1.6.0_16", paintComponent is runned two or three times.
if I run this program with "jre1.6.0_07", paintcomponent is runned just one time. (That is good for my use).

Is it possible to run paintComponent only one time under "jre1.6.0_16".

I seems this modification is between "jre1.6.0_7" and "jre1.6.0_10".
