vRO 7.0 Appliance Error - "ch.dunes.model.type.ConvertorException: Missing class to decode object"

I recently built a new vRO 7.0 appliance in my environment so that I could evaluate rolling it out in my organization.  After setting the device up, I noticed the following error coming from several workflows:

ch.dunes.model.type.ConvertorException: Missing class to decode object

I had no idea what this meant so I had to open a case with Vmware Tech support.

Turns out, it's a known issue with a simple fix:

• Log onto the Appliance via SSH
• Run this command

   vi /usr/lib/vco/app-server/bin/setenv.sh

• Edit the JVM_OPS variable and add the following to the end: 

-Dsun.lang.ClassLoader.allowArraySyntax=true

The end result should look like this:

- Reboot the appliance

Hopefully this saves someone some time down the road.
