A DESCRIPTION OF THE PROBLEM :
I have a Lotus Notes database that I access as a web application. The Domino server makes use of a Java applet to display buttons of a Notes view when it is accessed via the web. JVM versions prior to 1.6.0_10 and 1.6.0_11 has the buttons displayed and functioning correctly (for example 1.6.0_7 was working fine), however, everytime I have 1.6.0_10 or 1.6.0_11 enabled, the buttons are no longer there, and whenever you click the blank area where the buttons are supposed to be, it brings up a sun java console with the following error message:

*******************************************************************************
