Kotlin issues (companion object)

從 App_Resources/Android/src/main/java 中的 Kotlin 範例和連結的 ns-android-kotlin.zip 範例專案開始。執行示範應用程式，檢查主控台輸出中的 companion-object 欄位，並將其與可正常運作的欄位和方法進行比較。當可以依預期從 NativeScript 存取 @JvmField 和 const 值時，即表示完成。

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 8.6.5
• Cross-platform modules: 8.6.2
• Android Runtime: 8.6.1 (also 8.7.0-alpha.1)
• iOS Runtime (if applicable): -
• Plugin(s): -

Describe the bug
I tried to do some basic stuff with Kotlin stuff inside a NativeScript app (as I have no experience with Kotlin development) and I am experiencing some issues with companion objects.

I added this Kotlin file to App_Resources/Android/src/main/java

// KotlinTest.kt
package com.example

class KotlinTest {
    val hello = "Hello from Kotlin!"    //working

    @JvmField
    val instanceTestField : Int = 1234  //working

    companion object {
        @JvmStatic
        fun increment(num: Int): Int {  //working
            return num + 1
        }

        @JvmField
        val message : String = "Hi!"    //not working

        const val VERSION = 9           //not working
    }
}

And I am trying to access the values like this in the NativeScript app:

const testObject = new com.example.KotlinTest();

console.log(testObject.hello);                    //working
console.log(testObject.instanceTestField);        //working
console.log(com.example.KotlinTest.increment(5)); //working

console.log(com.example.KotlinTest.message);      //not working
console.log(com.example.KotlinTest.VERSION);      //not working

As far as I can read here about @JvmField annotation and here about const modifier this is valid Kotlin so it also shold work in NativeScript, but I always get undefined for those elements.

To Reproduce
Start the demo app provided below and check the logs in console.

Expected behavior
JvmFields and const values inside companion objects should be accessible in NativeScript.

Sample project
ns-android-kotlin.zip
