i'm trying to call a jdbi-method from kotlin, and i get:

Type inference failed: Not enough information to infer parameter X in 
fun <R : Any!, X : Exception!> withHandle(callback: ((handle: Handle!) → R!)!): R!
Please specify it explicitly.

the method signature is

public <R, X extends Exception> R withHandle(HandleCallback<R, X> callback) throws X {

what am i supposed to do in this case?

What is your code? Did you try to just specify types explicitly?

just the example from the jdbi page:

val names = jdbi.withHandle({ handle ->
            handle.createQuery("select name from contacts")
                    .mapTo(String::class.java)
                    .list()
        })

i don't know how to specify the type of the exception

jdbi.withHandle<R, Exception>

?

🤔
