Review of simple java app

Note:Budget no more then 10 For This 10 Min Work. General information for the business: Simple Java App Needs Reviewed Description of requirements/functionality: We have a small custom-built Java app that we use for training students. For some reason it is not working on our new VM. We just need someone to review the set-up and make any necessary changes. It is likely to be something in the set up of the VM, not a problem with the App.
