[SOLVED] problems getting mockservicerunner.sh started

So our group has been a user of SoapUI for a few years now and on one of our dev servers, we use the mockservicerunner.sh to mock many of the backend systems that our code connects to. This is on a linux box and we're running it via commandline.

With that said, we were using SoapUI version 2.0.2 and wanted to update to version 4.0.1. Everything worked fine with the old version and we basically downloaded the binaries for the new version, changed the path, and started the service. But instead of the mock service starting like always, the service hangs for a few minutes and then the error below is displayed.

Can anyone provide some assistance or pointers for what to do with troubleshooting this issue? Any assistance would be much appreciated.
