Is the soapUI plugin source code available?

I'd like to see an example of how to create an OSGI loadUI plugin that embeds soapUI. (For whatever reason, loadUI will not load a soapUI project from a Groovy component - I get errors to the effect that EndpointStrategyConfigImpl cannot be cast to DefaultEndpointStrategyConfig ... this does not happen when loading a soapUI project from a Groovy script outside of loadUI ... I've seen similar issues in other apps that use OSGI ... so I'm guessing that the only way out is to play it the soapUI plugin way and put all of the soapUI dependencies into the same OSGI module as the code that embeds it.)
