    I'm excited to try compiling some clojure to run on my pi (running manjaro 64-bit). However I can't find any information on how to cross-compile to target aarch64. Can someone explain the process?

    https://www.graalvm.org/docs/graalvm-as-a-platform/implement-language/

    A language implemented with Truffle Language Implementation framework can be AOT compiled using the GraalVM Native Image. Running mvn package in the simplelanguage folder also builds a slnative executable in the native directory. This executable is the full SimpleLanguage implementation as a single native application, and has no need for a GraalVM in order to execute SimpleLanguage code.

    https://www.graalvm.org/docs/reference-manual/native-image/

    GraalVM native-image supports JVM-based languages, e.g., Java, Scala, Clojure, Kotlin. The resulting native image can, optionally, execute dynamic languages like JavaScript, Ruby, R, or Python, but it does not pre-compile their code itself.

    Does this information conflict with each other or does SimpleLanguage compile in the same way as Java?

    Dear fellow graal users,

    Is there a way to override an already overwritten method with graal.
    Since the ManagementFactory.getPlatformMBeanServer returns null,
    it would be nice if i could overwrite it so i could still use jmx api for reporting and write my own http backend to get the metrics out of the app.
    At compile time it fails since this class has already been substituded by graal itself.

    @TargetClass(java.lang.management.ManagementFactory.class)
    @SuppressWarnings("unused")
    final class ManagementFactory {
        @Substitute
        public static synchronized MBeanServer getPlatformMBeanServer() {
            return ReplacementServer.server;
        }
    }
    nvm i'm posting this to slack.

    Hello all,

    I am having an issue with compiling a micronaut application to a native image with graalvm. This issue relates specifically to using H2 within this application. I have created a small test api. It utilizes h2 and I believe is configured properly (although obviously something is wrong due to the issue I am having). When I run the application normally, everything runs as expected. Hikari starts, I see the hibernate log messages I expect, and the table I use gets created using the h2 dialect. I can then successfully build this application into a native binary image. The issue comes about when running this application with docker, I do not see the start up log messages I expect and I get a "Internal Server Error: No backing RepositoryOperations configured for repository. Check your configuration and try again" error message. I find this confusing because again, it works when I am running it as a non native image. Has anyone faced similar issues or are they aware of the cause?

    Hi there! Has anybody successfully built native image and run Java AWS SDK V2 samples?
    Now playing with com.example.dynamodb.ListTables in attemp to build native image: built jar, run it with -agentlib:native-image-agent anf gen META-INF/native-image/*-config.json files, rebuild jar and when run:

    native-image --no-fallback -H:+TraceClassInitialization -jar target/sdk-dynamodb-examples-1.0.jar

    got

    Error: Classes that should be initialized at run time got initialized during image building:
     org.apache.http.conn.ConnectionRequest the class was requested to be initialized at build time (from the command line). org.apache.http.conn.ConnectionRequest has been initialized without the native-image initialization instrumentation and the stack trace can't be tracked. Try avoiding to initialize the class that caused initialization of org.apache.http.conn.ConnectionRequest

    If add --initialize-at-build-time=org.apache.http then got dozens of another errors:

    The VMError.shouldNotReachHereand the fact that the same fatjar compiles with native-image on some runs tells me it's probably not related to my code

    The GraalVM native image compiler runs as a server - is it possible to run and use such a server remotely, eg, start a 96 CPU ec2 instance running the native image compiler server, and then have a developer machine connect to and use it to compile something?

    I have a question regarding native-image building. What happens to files like build.properties contained in jars on -imagecp? I ask this because I have jackson crashing because it cannot read a groupId from a build.properties which is in the jar of jackson-module-scala.
    Should I include these files with -H:IncludeResources=**/build.properties or is there a different canonical way to do this?
    And is there a way to inspect the native image to see which resources are actually included?

    Hi, is there any way to speed up a Docker based native-image build? I’ve created a simple REST service using Micronaut and it takes ~2 hours to build a native app with the following build options:

    FROM oracle/graalvm-ce:20.0.0-java11
    ...
    RUN native-image -J-Xmx10G -J-Xms2G --no-fallback --allow-incomplete-classpath --verbose -H:+ReportExceptionStackTraces --no-server -cp target/my-service-app.jar

    Not sure what else I can tune in there. Any help would be appreciated, Thanks!

    Hi all,
    I'm in the process of automating native image build for multiple OSes using GitHub Actions. To start simple, I created a repository with the simplest HelloWorld, works great for Linux and macOS builds, but I'm stuck with Windows build. I'm using Maven and the `native-image-maven-plugin` plugin to call native-image, but it keeps giving me this error: Image building on Java 11+ without native-image requires MAVEN_OPTS='--add-exports=java.base/jdk.internal.module=ALL-UNNAMED'. It looks like the GraalVM setup is OK, though, as the PATH contains "C:\hostedtoolcache\windows\GraalVM\20.1.0-java11\x64\bin" JAVA_HOME is "C:\hostedtoolcache\windows\GraalVM\20.1.0-java11\x64" and `java -version` gives me this output:
    openjdk version "11.0.7" 2020-04-14
    OpenJDK Runtime Environment GraalVM CE 20.1.0 (build 11.0.7+10-jvmci-20.1-b02)
    OpenJDK 64-Bit Server VM GraalVM CE 20.1.0 (build 11.0.7+10-jvmci-20.1-b02, mixed mode, sharing)
    I tried both version 19.3.2 and 20.1.0
    Native image installation looks OK, with command: %JAVA_HOME%/bin/gu.cmd install native-image
    I'm running maven from the VS dev command prompt, using:
    call "C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Auxiliary\Build\vcvarsall.bat" x86_amd64
    mvn -B package --file pom.xml
    Am I missing something here? Should I drop the maven plugin and call native-image manually in my GitHub Action?
    Thanks!

    Hi!
    I'm using Micronaut 2.0.0-M3 & Graal-CE 20.1.0 but getting the below CNF trying to DNS lookup via InitialContext running my native-image.

    Any thoughts what is missing?
