[Native Image] Error: java.lang.NullPointerException: Cannot invoke "com.oracle.graal.pointsto.flow.context.object.AnalysisObject.type()" because "object" is null

[nreid260]

Describe the Issue

We're transforming the Kotlin compiler (actually a wrapper around it) into a Graal native-image executable. The whole setup for this is pretty complicated and in a proprietary repo, so I can't give a good reproduction. I'm hoping that the bug will be obvious to someone who knows the code.

When we run the transformation, it crashes with java.lang.NullPointerException: Cannot invoke "com.oracle.graal.pointsto.flow.context.object.AnalysisObject.type()" because "object" is null

Using the latest version of GraalVM can resolve many issues.

• I tried with the latest version of GraalVM.

GraalVM Version

GraalVM 23.0.1

Expected Behavior

The transformation should succeed, emitting a native executable for the original program.

Actual Behavior

Warning: Option 'DynamicProxyConfigurationResources' is deprecated and might be removed in a future release: This can be caused by a proxy-config.json file in your META-INF directory. Consider including proxy configuration in the reflection section of reachability-metadata.md instead.. Please refer to the GraalVM release notes.

### Steps to Reproduce

I can try to communicate more on this, but there are no realistic repro steps outside of our repository.

### Additional Context

_No response_

### Build Log Output and Error Messages

We can't much do without a reproducer, for now please check the following:

• Generating the Metadata files before building your native image, read more here

[nreid260]

So are you saying this is related to the reachability-metadata.json files? We noticed some changes in metadata collection between Graal 22 vs Graal 23, so maybe that's connected. We sample about 30 randomly selected build targets in our repo to try to get metadata coverage on the Kotlin compiler. With Graal 23 we had to add more sample targets to maintain coverage.

---

Are there flags for getting more info out of the points-to analysis? This seems like a bug, since were seeing an NPE rather than an intentional error message.

---

I guess, while I'm here, we also had issues with null Kotlin properties. Something like:

class Foo {
  fun test(): String? {
    return NULL_STRING
  }

  companion object {
    val NULL_STRING: String? = null
  }
}

[nreid260]

Thankfully the issue seems to be reproducible with only the reflect-config.json collected using the agent from our sample targets. None of our other flags or features are needed.

[thomaswue]

Thank you! We will look into this.

[cstancu]

@nreid260 thank you for the self contained reproducer. The NPE but also the underlying issue is fixed by #10104. With this patch the kotlin-compiler image builds successfully. Running it leads to a java.lang.NoSuchMethodException: org.jetbrains.kotlin.cli.common.arguments.CommonCompilerArguments.getStdlibCompilation() which I assume is because the reproducer is not including all expected registrations.

[nreid260]

We're still observing this in 23.0.2. Is it supposed to be fixed in that version?

[thomaswue]

Hi @nreid260! Thanks for reporting back. I see that the fix was backported. Do you also get the issue still also with the latest EA builds?

[nreid260]

Where would I download those from? Currently we're pulling https://github.com/graalvm/graalvm-ce-builds/releases/download/XXX/graalvm-community-XXX_linux-x64_bin.tar.gz
