Hello, Is there a mature example of creating a

java.lang.reflect.Proxy

for a Kotlin interface with

suspend

methods? (I would call the proxy methods only from Kotlin code.) Thanks.

You can look at the internals of Retrofit, but it's a bit abstracted

https://github.com/square/retrofit/blob/master/retrofit/src/main/java/retrofit2/HttpServiceMethod.java#L198-L237

Can start there

Retrofit is written in Java, but I suspect you might actually be required to have some Java even if your project is all Kotlin because you need to pass the continuation to the altered function signature

The

UndeclaredThrowableException

issue seems nasty.

Definitely surprising and took a while to debug. Got a good blog post out of it, though.
