SoapUI 5.6+ for Mac OS: Deploy as War using JDK 1.8

I would like to know if there is a way in SoapUI since 5.6.0 versions to deploy a project as war using JDK 1.8

The last version capable of this was 5.5.0

I would like to upgrade the software, but I need to make the deploy for environments using JDK 1.8

How can I do a deploy with JDK 1.8 with 5.6.0 and next?

Thanks in advance.
