I may miss something, but with following Java interface:

public interface Expression {

    @Nullable
	Object getValue(EvaluationContext context, Object rootObject) throws EvaluationException;

    @Nullable
	<T> T getValue(EvaluationContext context, @Nullable Class<T> desiredResultType) throws EvaluationException;
}

And following Kotlin code

val value = expression.getValue(context, String::class.java)

, the method used is the first variant, not the second (with IDEA 2019.2 and Kotlin 1.3.41). Why?

I had a similar problem with this.

Hum, any existing bug referenced? Sounds like a surprising and big interop issue.

I fixed by adding a when checking for the class type and the compiler got the right one... Lemme find it

Ok I will ask ok #general and if no more info I will create an issue

Yep... It does look like it's a inference thing... Once I made sure the of the viewClass class, it allowed it as a parameter and got the right override.

I tried to disable the new inference but same result
