OS - Solaris Sparc
browser - NS6.1, NS6.2.1
build - b04 (SWAT test build)

Steps to reproduce -

Step 1) Install hopper build 04 from

        /net/mizu.sfbay/usr/re/jdk1.4.1/bundles/solsparc/latest

Step 2) Make sure .java.policy file is there in $HOME.

Step 3) Register the plugin wth Netscape 6

Step 4) Invoke the vminfo applet from

      http://sqesvr.sfbay.sun.com/deployment1/ws/tests/func/vminfo/vminfo.html

Note - Similar behavior is seen when executing the cookie tests also with the same build.

The applet does not load and the following exceptions are thrown on Console -
