Issue with gradle and maven examples

[jchrisos]

Hi,

I'm trying to run gradle and maven examples and I'm getting an exception

Thank you,

Steps Maven:

• mvn install
• native-image --static --report-unsupported-elements-at-runtime -jar target/maven-example.jar = ok
• ./maven-example = exception

Steps gradle:

• gradle install = ok
• native-image --static --report-unsupported-elements-at-runtime -jar build/fatjar/example.jar = ok
• ./example = exception

My setup:
OS: Ubuntu 18.04 LTS
Java: 1.8.0_212

I tested in macos 10.14 and got same exception.

Exception in thread "DefaultDispatcher-worker-3" java.lang.ExceptionInInitializerError at com.oracle.svm.core.hub.ClassInitializationInfo.initialize(ClassInitializationInfo.java:287) at java.lang.Class.ensureInitialized(DynamicHub.java:437) at io.ktor.network.selector.SelectableBase.<init>(Selectable.kt:38) at io.ktor.network.sockets.ServerSocketImpl.<init>(ServerSocketImpl.kt:11) at io.ktor.network.sockets.TcpSocketBuilder.bind(Builders.kt:122) at io.ktor.network.sockets.TcpSocketBuilder.bind$default(Builders.kt:114) at io.ktor.server.cio.HttpServerKt$httpServer$acceptJob$1.invokeSuspend(HttpServer.kt:88) at kotlin.coroutines.jvm.internal.BaseContinuationImpl.resumeWith(ContinuationImpl.kt:32) at kotlinx.coroutines.DispatchedTask.run(Dispatched.kt:233) at kotlinx.coroutines.scheduling.CoroutineScheduler.runSafely(CoroutineScheduler.kt:594) at kotlinx.coroutines.scheduling.CoroutineScheduler.access$runSafely(CoroutineScheduler.kt:60) at kotlinx.coroutines.scheduling.CoroutineScheduler$Worker.run(CoroutineScheduler.kt:742) at com.oracle.svm.core.thread.JavaThreads.threadStartRoutine(JavaThreads.java:473) at com.oracle.svm.core.posix.thread.PosixJavaThreads.pthreadStartRoutine(PosixJavaThreads.java:193) Caused by: java.lang.RuntimeException: java.lang.NoSuchFieldException: readHandlerReference at java.util.concurrent.atomic.AtomicReferenceFieldUpdater$AtomicReferenceFieldUpdaterImpl.<init>(AtomicReferenceFieldUpdater.java:162) at java.util.concurrent.atomic.AtomicReferenceFieldUpdater.newUpdater(AtomicReferenceFieldUpdater.java:110) at io.ktor.network.selector.InterestSuspensionsMap.<clinit>(InterestSuspensionsMap.kt:61) at com.oracle.svm.core.hub.ClassInitializationInfo.invokeClassInitializer(ClassInitializationInfo.java:347) at com.oracle.svm.core.hub.ClassInitializationInfo.initialize(ClassInitializationInfo.java:267) ... 13 more Caused by: java.lang.NoSuchFieldException: readHandlerReference at java.lang.Class.getDeclaredField(DynamicHub.java:2070) at java.util.concurrent.atomic.AtomicReferenceFieldUpdater$AtomicReferenceFieldUpdaterImpl.<init>(AtomicReferenceFieldUpdater.java:157) ... 17 more

I fixed this by adding this argument to native-image: --initialize-at-build-time=io.ktor,kotlinx,kotlin,org.slf4j

Not sure if all of those are strictly necessary of if they can be made more specific but it worked for me
