[Native Image] Inspecting `Type.getTypeName` & `getAnnotation` yields errors

[JaroslavTulach]

Describe the Issue

I am trying to find out classes with a special annotation that get into native image heap and do something based on that annotation values. This seems to fail on GraalVM 24.0.1. See the attached demo project.

Using the latest version of GraalVM can resolve many issues.

• I tried with the latest version of GraalVM.

GraalVM Version

openjdk version "24.0.1" 2025-04-15
OpenJDK Runtime Environment GraalVM CE 24.0.1+9.1 (build 24.0.1+9-jvmci-b01)
OpenJDK 64-Bit Server VM GraalVM CE 24.0.1+9.1 (build 24.0.1+9-jvmci-b01, mixed mode, sharing)

Operating System and Version

Ubuntu

Build Command

Unzip NativeImageHeap.zip and then run:

JAVA_HOME=/graalvm-24/ mvn -f NativeInspectHeap/ clean install

the execution fails with

> jdk.graal.compiler.java.BytecodeParser$BytecodeParserError: com.oracle.graal.pointsto.util.AnalysisError: java.lang.UnsatisfiedLinkError: 'java.lang.String com.oracle.svm.core.hub.DynamicHub.getTypeName()'
        at parsing com.oracle.svm.core.hub.DynamicHub.fromClass(DynamicHub.java:782)
        at parsing com.oracle.svm.core.snippets.SubstrateIsArraySnippets.classIsArray(SubstrateIsArraySnippets.java:35)
        at parsing jdk.graal.compiler.replacements.IsArraySnippets.objectIsArraySnippet(IsArraySnippets.java:42)

Expected Behavior

• I believe all Type instances in the heap should properly implement getTypeName()
• I believe all Type instances that are also AnnotatedElement instances should implement getAnnotation
• definitely calling these methods shouldn't break the native-image compilation with interenal error

Actual Behavior

the execution fails with

> jdk.graal.compiler.java.BytecodeParser$BytecodeParserError: com.oracle.graal.pointsto.util.AnalysisError: java.lang.UnsatisfiedLinkError: 'java.lang.String com.oracle.svm.core.hub.DynamicHub.getTypeName()'

Hi @JaroslavTulach,

Thank you for reaching out to us about this.
Could you please share the reproducer with us using a github repo?

Thank you.

Could you please share the reproducer with us using a github repo?

Why? Please, follow these steps to execute the reproducer:

wget https://github.com/user-attachments/files/20983787/NativeImageHeap.zip
unzip NativeImageHeap.zip
JAVA_HOME=/graalvm-24/ mvn -f NativeInspectHeap clean install

Is it that hard to follow these three steps? What exactly a github repository would simplify on these steps?

Hi @JaroslavTulach,

As part of our security policy, we require a GitHub repository so we can review the code and files before downloading them. However, I was able to get an exception approved in your case, so we’ll proceed with the ZIP file you provided.

Thank you for your understanding!
