Error during parentOfType

Hi,

I got a small IntelliJ plugin using Kotlin version 1.3.31. When the plugin calls

val parent = element.parentOfType(JSObjectLiteralExpression::class)

the IDE reports an error:

java.lang.ClassCastException: kotlin.jvm.internal.ClassReference cannot be cast to kotlin.jvm.internal.ClassBasedDeclarationContainer
	at kotlin.jvm.JvmClassMappingKt.getJavaClass(JvmClassMapping.kt:28)
	at com.intellij.psi.util.PsiTreeUtilKt.parentOfType(psiTreeUtil.kt:11)

Now I am wondering what I can do to resolve this issue. The exception is thrown within Kotlin / IntelliJ code. Can you help me out here?

Thanks,

Matthias

Another hint - wenn adding kotlin-reflect to the class path, the error message changes to:

kotlin.reflect.jvm.internal.KClassImpl cannot be cast to kotlin.jvm.internal.ClassBasedDeclarationContainer

This issue occurrs only in newer IntelliJ versions (IU-2018.3 still works, IU-2019.1.1 is broken).

Hi Matthias,

had the same issue with my plugin. Reason was a bundled kotlin jar within my plugin package. If so, remove it from your plugin.
Kotlin should not included in any plugin as mentioned in the SDK / https://www.jetbrains.org/intellij/sdk/docs/tutorials/kotlin.html 

Regards,

Thomas
