OutOfMemoryError While Loading Test Cases

Hello,

I have created a testpack with combines a SOAP & REST service, with a groovy script to go to one of our databases to build up the information required for the XML Request for the REST service. However, after opening 5 test cases, I receive an OOM error. Closing test cases does not reduce the memory used, and running a garbage collection also does not reduce the memory used.

Other than killing the process I can't seem to work out why it is doing this.

Below is the stack trace from the error log. I've checked soapui-errors.log, and soapui.log and errors.log and found nothing there, I've also tried increasing the -Xmx value and it still doesn't work. Any ideas?
