Java allows root access without permission?

Fedora 13 x86_64 with OpenJDK (not Sun) installed.

I was required to login to a web site today to configure a VPN and the 
site installed a Cisco VPN Java applet. When it was finished installing 
and was running I noticed the processes where running as root and had 
installed into /opt. I had not given it my root password or any 
permission to do so. It did not install any RPM package. It was all 
driven by a Java applet.

$ ps -efw #id 502 is me
502       4791  2668  0 11:16 ?        00:00:19 
/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/lib/amd64/../../bin/java 
sun.appl
root      4923     1  0 11:16 ?        00:00:00 /opt/cisco/vpn/bin/vpnagentd

Is this something "allowed" by some configuration setting in OpenJDK 
somewhere? I'd like to turn off this "feature" ASAP.

Thanks,
Michael
