Errors launching SoapUI 5.5.0

I'm very new to SoapUI and not yet familiar with all the ins and outs.  Similar to another post here within the last day I am getting errors that I did not notice yesterday, or even this morning, when simply starting up SoapUI:

When I check the error.log file the two errors below are repeated 10x:

At the same time my CPU usage bounces around sporadically, especially when running a simple GET request.  On an i7-6700 CPU the usage goes as high as 82%.  I've restarted my machine twice this afternoon with no change.  SoapUI is currently frozen after initiating another simple GET request.  I've had to kill it multiple times via the Task Manager.

Any thoughts?

Thanks
