Import postman collections to SoapUi

I assume you're referring to the fact that when you try to import it, you get something like:

    net.sf.json.JSONException: JSONObject["requests"] is not a JSONArray.

As this is apparently open source, I would consider stepping through this code to see whether it's practical to fix. It's not clear exactly what open source components are in play here. I noticed both https://github.com/SmartBear/soapui and https://github.com/SmartBear/readyapi-postman-plugin . I don't see any sign in the soapui code of any way to import Postman collections (I've looked at a couple of different branches, including "release-5.7.2"). The plugin seems it could be where it's done, but I don't understand how that is integrated into soapui, and that is apparently for "Ready API", not the open source SoapUI. The plugin docs refer to an "Integrations" tab in SoapUI, which I don't see in 5.7.2.

It appears that SoapUI 5.7.2 comes with version 1.0.1 of the readyapi-postman plugin. That appears to correspond to a commit made 8 years ago. Is there any way to know what the compatibility matrix is? Would a more recent version of the plugin work with both the more recent postman versions and this apparently older soapui release?  I have a feeling no one who would have these answers is going to see this.
