Have anyone tried soapui 5.6.0 with xmlbeans 5.0.3

The soapui 5.6.0 is dependent on xmlbeans "3.1.1-sb-fixed" which appears a customized xmlbeans version. In a unique situation where our web application would also use another library that needs xmlbeans 5.0.3. But the problem is obvious and we can't have two versions of xmlbeans in the classpath or we have runtime issues finding the appropriate binaries.

If we carefully modify the soapui src to use xmlbeans 5.0.3 would we be OK? Trying to see if someone else ventured this route.

Thanks
