Hi,
I am getting an error under Eclipse and I do not know how to fix it.
when I try to build from http://start.spring.io/ "Generate a Gradle Project with Kotlin and Spring Boot 2.0.0 m7"

Import Project -> waiting -> find class containing "fun main"😄 -> and run As -> Kotlin Application ->I get an error:

EXCEPTION: org.jetbrains.kotlin.codegen.CompilationException: Back-end (JVM) Internal error: Couldn't inline method call 'runApplication' into
public fun main(args: kotlin.Array<kotlin.String>): kotlin.Unit defined in pl.app.app[SimpleFunctionDescriptorImpl@636cba5e]
fun main(args: Array<String>) {
    runApplication<AppApplication>(*args)
	val x = args.joinToString()
    println("sasasa $x")
}
Cause: Not generated
Cause: Cannot inline bytecode of class org/springframework/boot/SpringApplicationExtensionsKt which has version 52. This compiler can only inline Java 1.6 bytecode (version 50)
File being compiled and position: (10,5) in G:/praca/spring/app/src/main/kotlin/pl/app/app/AppApplication.kt
PsiElement: runApplication<AppApplication>(*args)
The root cause was thrown at: InlineCodegenUtil.java:157
	at org.jetbrains.kotlin.codegen.inline.InlineCodegen.throwCompilationException(InlineCodegen.java:203)

when I start using ./gradlew bootRun is fine

what am I doing wrong?
