Property "javaplugin.vm.options" used to return valid values against the valid and secure set of runtime arguments/properties but that's not true anymore. FOr example when -Xint is passed as runtime arg then "javaplugin.vm.options" used to retunr "-Xint" on all the configs but right now it's returning null.
Issues is reproduced mainly on VISTA and unix machines

Steps to reproduce:
--------------------
1) Try to load the following applet http://sqeweb.sfbay.sun.com/deployment2/jitu/deployment_mustang_exec_ws/deployment/src/plugin/runtimeArgs/runtimeArgs/html/auto/IntegratedMode/TestRuntimeArgsXint.html

If inside the signed applet area , nothing is getting displayed against "Vm options" then bug is reproduced
