Subject: Am I also suffering from this security problem?

Dear Java team,

For a couple of months already, I am trying to get Java working for my
enterprise. I am based in the Netherlands and my business is closely
related to the design and manufacturing in the automotive industry.

At first, I downloaded JDK1.0.2. I am especially interested in
development in the CADCAM area. With JDK1.02 all applications developed
up to that time, worked fine. However, after the download of JDK1.1.1 I
am having serious problems when I'm trying to get the awt related
programs working. For my applications, especially the mouse events are
important. They all compile without problems, but when I try to run them
using the html program on the web page, the same error message is
popping up all the time. For example, when trying your sample applet
MouseDemo, the message states:

"Applet can't start: class MouseDemo got a security violation:
method verification error"

This happens even, when I'm trying to have your own original applet run
on your web site. So, first of all I was wondering if it would be my
mouse or other system settings. However, having read your statements
about what you describe as some kind of a security type of bug, I
thought this could be be the cause as well. To allow me to continue my
developments in Java, please, let me know if I am indeed suffering from
this bug, or that I am doing something wrong myself. You can imagine
that it is a little frustrating, having so many ideas to implement using
your great new language, and just being held up by this nasty little
problem. Please, try to give me a hint.

P.S. I noticed that when I uncomment the switch(e.getID()) statement,
the error is gone (however the program doesn't function anymore, of
course).

Thanks in advance for your help,
