Graalvm 22.2.0 fails to build mockwebserver in native image

[avimalka]

Hi,

When trying to build mockwebserver with native image on Graal 22.2 it fails with the following:

Fatal error: java.lang.IllegalAccessError: class okhttp3.internal.graal.OkHttpFeature (in unnamed module @0x13ed066e) cannot access class com.oracle.svm.core.configure.ResourcesRegistry (in module org.graalvm.nativeimage.builder) because module org.graalvm.nativeimage.builder does not export com.oracle.svm.core.configure to unnamed module @0x13ed066e

Older version works perfectly. Any workaround / solution for this ?

[yschimke]

Which version of OkHttp are you on? 4.10?

I can bump the version in 4.10.1? and see if that fixes this.

Thanks for reporting.

[avimalka]

I'm using 5.0.0-alpha.5. Should I use version 4. ? the documentation says version 5. should be used for Graalvm native-image

[yschimke]

Yep, can you try alpha.10? I'll check this week.

[avimalka]

alpha.10 has the same error

Testing with https://github.com/square/okhttp/pull/7409

[yschimke]

Looks like a common problem affecting frameworks like Quarkus. Two workarounds

1) export USE_NATIVE_IMAGE_JAVA_PLATFORM_MODULE_SYSTEM=false 2) Add options

-J--add-exports=org.graalvm.nativeimage.builder/com.oracle.svm.core.jni=ALL-UNNAMED 
-J--add-exports=org.graalvm.sdk/org.graalvm.nativeimage.impl=ALL-UNNAMED 
-J--add-exports=org.graalvm.nativeimage.builder/com.oracle.svm.core.jdk=ALL-UNNAMED 
-J--add-exports=org.graalvm.nativeimage.builder/com.oracle.svm.core.jdk.localization=ALL-UNNAMED 
-J--add-exports=org.graalvm.nativeimage.base/com.oracle.svm.util=ALL-UNNAMED

[yschimke]

Raised https://github.com/oracle/graal/issues/4787 for a build failure on one target, but okcurl is building, so partially working.

USE_NATIVE_IMAGE_JAVA_PLATFORM_MODULE_SYSTEM seems like the current fix. We are now on 22.3.0

[fniephaus]

I'm afraid using USE_NATIVE_IMAGE_JAVA_PLATFORM_MODULE_SYSTEM is only a temporary workaround as it will soon be removed. It seems OkHttpFeature.kt is still depending on internal GraalVM Native Image API:

https://github.com/square/okhttp/blob/76331ffe0024d5f8ca2f88a32c6ed3185a3ab716/okhttp/src/jvmMain/kotlin/okhttp3/internal/graal/OkHttpFeature.kt#L19-L20

Instead, the feature should use RuntimeResourceAccess and other classes of the public GraalVM SDK that we introduced in 22.3. Note that AutomaticFeature is not part of the public API. Instead, I think the feature can add itself with --feature=okhttp3.internal.graal.OkHttpFeature via its native-image.properties.

[yschimke]

@fniephaus I'll take a look, that's for the detailed pointers.

[yschimke]

Fixed in https://github.com/square/okhttp/pull/7703/files

[GrapeBaBa]

@yschimke I still got this issue, with graalvm 22.3.1, jdk19. okhttp 5.0.--alpha.11

[yschimke]

will need the next alpha release https://github.com/square/okhttp/issues/7883

Snapshots are available if you want to test, or it's really blocking you
