SoapUITestCaseRunner - NullPointerException

I am using the no-pro version of soapUI. I have created a suite of test cases. Each test case successfully runs on its own, but I get a NullPointerExcption when I attempt to launch in TestRunner. The soapUI TestRunner window is not allowing me to copy and paste the output.

Ideas on what is causing the NullPointerException?

Here's the INFO log statement with the NullPointerException
