kotlinlang #eap

I searched the issue DB but recently I've not been so successful in finding relevant ones despite it's already there. 🙂 So I just wanted to know if anyone is experiencing similar before filing an issue. Anyway, I'll try to isolate the issue and file an entry to Kotlin Youtrack.

@sdeleuze can it be you have 1.0.6 installed into IDEA?

Interesting thing I experienced during preparation of the code for reproducing the bug is I had to put

compile

dependency on the annotation processor to make it work under

1.0.6

. That was not the case for my current project. Maybe I'm missing something.

Anyway as seen in the example project, it's not only mine but also Google's that shows the same problem in 1.1-beta.

I'd be really happy if there is any workaround for this problem. We hope to leverage some 1.1 features immediately. 🙂

@orangy No I have 1.1-beta-17 Kotlin plugin

sdeleuze

01/24/2017, 7:54 AM

I will try to reproduce in a smaller project

@sdeleuze change target platform to 1.8 in Kotlin facet or use compiler option '-jvm-target 1.8'

sdeleuze

Ok thanks I will try. My goal is to make it work without modifying manually IDEA configuration so I will try with complier options

@max.kammerer I have added this to my gradle build to make sure that Kotlin produces 1.8 byte code:

sdeleuze

01/24/2017, 12:05 PM

Copy code

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

sdeleuze

01/24/2017, 12:06 PM

And now I got the same error when running a build with Gradle:

sdeleuze

01/24/2017, 12:06 PM

Copy code

:spring-context:compileTestKotlin

We want to generate 1.8 bytecode for both Java and Kotlin

sdeleuze

01/24/2017, 12:07 PM

So this is likely an option we want to set

sdeleuze

01/24/2017, 12:07 PM

But I don’t know why I get this message about the compiler non supporting inlining with 1.8 bytecode ...

sdeleuze

01/24/2017, 12:08 PM

Inlining is supported for both Java 6 and Java 8 bytcode, isn’t it ???

sdeleuze

01/24/2017, 12:09 PM

This error is like if Kotlin could inline Java 6 byte code compiled from a Kotlin file into a Java 8 bytecode compiled form Java 8

sdeleuze

01/24/2017, 12:10 PM

But not Java 8 bytecode compiled from Kotlin into Java 8 bytecode compiled from Java 8

sdeleuze

01/24/2017, 12:10 PM

I would have understood the opposite

sdeleuze

01/24/2017, 12:10 PM

But here I don’t really understand, any hints?

udalov

01/24/2017, 12:26 PM

This error only happens if the compiler attempts to inline Java 8 bytecode into Java 6 bytecode

udalov

01/24/2017, 12:28 PM

BTW, you can pass a JVM property

-Dkotlin.skip.bytecode.version.check=true

to the process where the compiler is being run to skip this check, but this obviously may lead to VerifyError etc

@sdeleuze could you provide sample project?

sdeleuze

01/24/2017, 12:39 PM

@max.kammerer Sure, just clone https://github.com/sdeleuze/spring-framework and run

./gradlew clean compileTestJava

./gradlew clean compileTestKotlin

sdeleuze

01/24/2017, 12:40 PM

@udalov Hum strange, Spring Framework 5 is likely to produces Java 8 bytecode … I am going to double check the bytecode we produce

sdeleuze

01/24/2017, 1:02 PM

I have checked, both

GenericApplicationContext.class

and

GenericApplicationContextExtensionsKt.class

have bytecode version 52 (Java 8)

ilya.gorbunov

@sdeleuze Does this error happen in test file? Then you might need to setup

jvmTarget

also in

compileTestKotlin

task.

sdeleuze

01/24/2017, 1:08 PM

Oh good point
