Expected Behaviour

The native image build should succeed

Actual Behaviour

Native image build fails with error:

.Example error (but not comprehensive)

Error: Classes that should be initialized at run time got initialized during image building:
 io.micrometer.shaded.io.netty.util.internal.PlatformDependent was unintentionally initialized at build time. To see why io.micrometer.shaded.io.netty.util.internal.PlatformDependent got initialized use -H:+TraceClassInitialization
io.micrometer.shaded.io.netty.util.internal.PlatformDependent0 was unintentionally initialized at build time. To see why io.micrometer.shaded.io.netty.util.internal.PlatformDependent0 got initialized use -H:+TraceClassInitialization

Environment Information

• Operating System: Ubuntu 20.04
• Micronaut Version: 2.5.0
• JDK Version: GraalVM ce Java 11 20.2.0

Example Application

https://github.com/brianwyka/micronaut-graal-micrometer-statsd

Steps to Reproduce

./mvnw package -Dpackaging=native-image

Attempted Resolutions

Updated the native-image.properties configuration to include:

--initialize-at-build-time=io.micrometer.shaded.io.netty.util
--initialize-at-build-time=io.micrometer.shaded.io.netty.util.concurrent
--initialize-at-run-time=io.micrometer.shaded.io.netty.util.internal.logging.Log4JLogger

Then results in this:

Error: Image build request failed with exit status 1

The build succeeded when I removed the io.micronaut.micrometer:micronaut-micrometer-registry-statsd dependency.

@ilopmar, seems like your area 🥇

[cohenor]

Hey, would be glad to know if there's any progress on this issue please 🙏
I'm experiencing the same behavior with Micronaut 3.2.3 and JDK GraalVM CE 21.3.0 (Java 17.0.1).
@brianwyka Were you able to work around this somehow?

Thanks.

[brianwyka]

Sorry @cohenor, I have not tried this since the failure, nor have I worked on a workaround.

Gotcha, thanks for your response.

[graemerocher]

The issue is that by shading Netty all of the GraalVM native config has to be re-applied to the native version. A feature would need to be added like this one https://github.com/micronaut-projects/micronaut-core/blob/1a15f0b5aba53da56f8915fc904ae4b7512e6f15/http-netty/src/main/java/io/micronaut/http/netty/graal/HttpNettyFeature.java and
