IllegalAccessError when using Instant Run with Kotlin

Question

I got this exception after I run the project using Instant Run:

java.lang.IllegalAccessError: Illegal class access: 'com.alla.kotlinexample.MainActivity$override' attempting to access 'kotlin.jvm.internal.DefaultConstructorMarker' (declaration of 'com.alla.kotlinexample.MainActivity$override' appears in /data/data/com.alla.kotlinexample/files/instant-run/dex-temp/reload0x0000.dex)
at com.alla.kotlinexample.MainActivity$override.onCreate(MainActivity.kt:21)
at com.alla.kotlinexample.MainActivity$override.access$dispatch(MainActivity.kt)

Here is the code:

class MainActivity : AppCompatActivity() {  

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        setSupportActionBar(toolbar)

        val persons: List<Person> = listOf<Person>(Person("Person1"), Person("Person2", 27))

        fab.setOnClickListener { view ->
            Snackbar.make(view, persons[1].name, Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show()
        }

        tv_person_name.text = persons.maxBy { it.age ?: 34 }.toString()
    }

    data class Person(val name: String, val age: Int? = null)


}

And the error points on this line val persons: List<Person> = listOf<Person>(Person("Person1"), Person("Person2", 27))

I had a similar problem when I used @JvmOverloads on my constructors. However it looks like when instead I define the constructors myself Instant Run works:

Instead of:

class StaticRefreshAnimationView @JvmOverloads constructor(
        context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0
) : LottieRefreshAnimationView(context, attrs, defStyleAttr) {

I use now:

class StaticRefreshAnimationView(context: Context, attrs: AttributeSet?, defStyleAttr: Int) :
        LottieRefreshAnimationView(context, attrs, defStyleAttr) {
    constructor(context: Context, attrs: AttributeSet?) : this(context, attrs, 0)
    constructor(context: Context) : this(context, null)
