`getJavaWildcard` does not account for overrides

When a java source overrides a kotlin file, inherited functions should also inherit the variance even when the overrider’s type deos not require it (e.g. it is final)

repro test: https://github.com/yigit/ksp/commit/a2b4324a0d50258a75e204237254f8c3d8188b89

Inputs:

// FILE: javaOverridesKotlin.kt
package main
interface BaseKotlinOverriddenByJava<T> {
    fun receiveReturnT(t: T): T
    fun receiveReturnTList(t: List<T>): List<T>
}

interface KotlinOverriddenByKotlinOpen : BaseKotlinOverriddenByJava<Number> {
}
interface KotlinOverriddenByKotlinFinal : BaseKotlinOverriddenByJava<String> {
}
// FILE: main/JavaOverridesKotlinOpen.java
package main;
import java.util.List;
public interface JavaOverridesKotlinOpen extends BaseKotlinOverriddenByJava<Number> {
}
// FILE: main/JavaOverridesKotlinFinal.java
package main;
import java.util.List;
public interface JavaOverridesKotlinFinal extends BaseKotlinOverriddenByJava<String> {
}

the signature of receiveReturnTList as member of JavaOverridesKotlinFinal (or KotlinOverriddenByKotlinFinal) still needs to return out variance for the String type parameter.

Looks like I have the same issue with room + ksp with base interface for DAO`s

Do you still have this problem with room 2.4.1? We couldn’t use the KSP API but implemented a custom one in room. If it is still not working for your case, it would be great to have a bug report so we can fix it in room. 🙏
