[native-image] MalformedParameterizedTypeException when using Kotlin

[nanodeath]

I'm running the following command and getting a crash. Compiled using Graal 1.0.0 RC and Kotlin 1.2.40.

    Error: Processing image build request failed

Unfortunately I can't attach source or JARs (as they're company IP), but if there's any other way I can provide more context, please let me know.

Thanks!

Thank you for your report. It would help if you could reproduce this with a minimal, non-proprietary, example. The MalformedParameterizedTypeException is thrown from java.lang.Class.getGenericInterfaces() which is

Thrown when a semantically malformed parameterized type is encountered by a reflective method that needs to instantiate it. For example, if the number of type arguments to a parameterized type is wrong.

This doesn't seem to be a SubstrateVM issue but rather an application issue. My guess is that you have some class path configuration problems (e.g., incompatible versions of the same jar on the class path).
To find the offending class you can debug the image building process for your app. See Building images for details. Hint: you don't actually need to build native-image from source; just use --debug-attach[=<port>] and do a remote debugging from your IDE (default port is 8000) but you still need the sources.

Messing around with the classpath a bit, if I remove kotlin-stdlib-1.2.40.jar I get java.lang.ClassNotFoundException: kotlin.jvm.functions.Function0, but if I add it back I get the same stacktrace as listed above. So my current unfounded theory is that it's related to that particular JAR.

I'll try what you suggested.

[nanodeath]

That was...surprisingly easy to set up, actually. I'm kinda shocked.

Anyway, the exception seems to happen when Inflation (at L240) hit the following class:

So I'm working on a repro for that.

[cstancu]

You can try calling java.lang.Class.getGenericInterfaces() directly on that class from within your app, with the same setup. I expect you will get the same exception.

[nanodeath]

Indeed, you're correct. I've created a Kotlin application from scratch and run the following:

import kotlin.reflect.jvm.internal.impl.protobuf.GeneratedMessageLite.*

fun main(args: Array<String>) {
    ExtendableMessage::class.java.genericInterfaces
}

which fails even on the standard Oracle JVM.

Correct me if I'm wrong, but this seems like an issue I should raise with JetBrains, correct?

[cstancu]

That's correct since JetBrains is the developer of kotlin-reflect. Glad you got to the bottom of this. I will close this issue, but let us know if you are successful in running your app on SubstrateVM.
