Enabling Javascript in the JXBrowser

I have some values that I need to read that are only returned from my HTTP Request in Javascript is enabled. However, I believe this is only going to be possible if the JXBrowser is available.

The problem I have here is that I can only get soapUI to come up at all if I disable the JXBrowser in the startup script (plenty of threads on this). I'm sing Windows 64-bit and Ubuntu. Is there ANY way around this so that I can move forward? If there is a workaround we're willing to buy multiple licenses.

Thanks
