Kotlin compiler issue with overriding of Java final function in Kotlin

I’m dealing with following issue with Kotlin/Java Compiler. Imagine following scenario: let First be a Java class with a final function and Second be a Kotlin class extending First with a function of the same name like the final function in First class, example:

// Java class
class First {
    final void foo() { }
}

// Kotlin class
class Second: First() {
    fun foo() { }
}

Obviously, it’s wrong because the final function foo() can not be overridden. However, compilation pass successfully and in run-time I get java.lang.LinkageError: Method void Second.foo() overrides final method in class First. Is this correct behavior of compiler? I supposed that there will be some validations for this case. Thank you!
