Looks promising, but I get as far as here and then get Exception in thread "main" jdk.vm.ci.common.JVMCIError: expected VM constant not found: CardTableModRefBS::dirtycard at jdk.internal.vm.ci/jdk.vm.ci.hotspot.HotSpotVMConfigAccess.getConstant(HotSpotVMConfigAccess.java:84) at jdk.internal.vm.ci/jdk.vm.ci.hotspot.HotSpotVMConfigAccess.getConstant(HotSpotVMConfigAccess.java:98) at jdk.internal.vm.compiler/org.graalvm.compiler.hotspot.GraalHotSpotVMConfig.(GraalHotSpotVMConfig.java:557) at jdk.internal.vm.compiler/org.graalvm.compiler.hotspot.AOTGraalHotSpotVMConfig.(AOTGraalHotSpotVMConfig.java:34) at jdk.internal.vm.compiler/org.graalvm.compiler.hotspot.HotSpotGraalRuntime.(HotSpotGraalRuntime.java:111) at jdk.internal.vm.compiler/org.graalvm.compiler.hotspot.HotSpotGraalCompilerFactory.createCompiler(HotSpotGraalCompilerFactory.java:132) at jdk.aot/jdk.tools.jaotc.Main.run(Main.java:144) at jdk.aot/jdk.tools.jaotc.Main.run(Main.java:101) at jdk.aot/jdk.tools.jaotc.Main.main(Main.java:80) The exact command I am executing is ed at ubuntu:~/openjdk$ /home/ed/openjdk/hs/build/linux-aarch64-normal-server-release/images/jdk/bin/jaotc -J--module-path=/home/ed/openjdk/graal/sdk/mxbuild/modules/org.graalvm.graalsdk.jar:/home/ed/openjdk/graal/truffle/mxbuild/modules/com.oracle.truffle.truffleapi.jar -J--upgrade-module-path=/home/ed/openjdk/graal/compiler/mxbuild/modules/jdk.internal.vm.compiler.jar Queens.class --Output Queens.so My JAVAHOME is ed at ubuntu:~/openjdk$ echo $JAVAHOME /home/ed/openjdk/hs/build/linux-aarch64-normal-server-release/images/jdk Any ideas? Thanks,

You must have built Graal with an old JDK. This is the line in question:

public final byte dirtyCardValue = isJDK8 ? getFieldValue("CompilerToVM::Data::dirty_card", Byte.class, "int") : getConstant("CardTableModRefBS::dirty_card", Byte.class);
