New error after recent java update on Mac

Question

Hi,
We run a learning management system that uses LiveConnect to communicate between the elearning module and the LMS.
Recently all sorts of things started going wrong, around the time of the latest update.
I just tried it from my Leopard-OS imac running Safari 3.1.2
Learning modules will no longer launch, and the following errors show up in the console.
If I launch from Safari, I get:

We're facing the same trouble, we have a very similar stack trace and the error occurs only with Safari v 3.2.1; no firewalls and no domains, the issue is related with this snippet of java applet code compiled against jdk v 1.4.12:
new PropertyResourceBundle(MyToolbar.class.getResourceAsStream("toolbar.properties"));
where the execution of getResourceAsStream throws a NPE.
"toolbar.properties" is a property file within the applet jar, the applet tries to acces such file with the execution of this line but fails.
This error happens with Safari and Google Chrome,
while it works fine with IE7, Firefox 2 and 3
the stacktrace contains the following lines:
