Proxy-ing problems when used with Kotlin data classes

[joffrey-bion]

I'm using DocxStamper from Kotlin, and my context for templating is basically full of data classes.

Data classes are final and don't have a 0-arg constructor. Both of which seem to be necessary when using DocxStamper, at least for complex comment-processored stuff from what I see.

Could you please explain why proxies are needed here? Is there a way for me to work around the problem?

In fact, even without a data class, when providing a default no-arg constructor and making the class non final, the proxy doesn't seem to provide data when processing comments... weird.
