2 weeks ago Hi @cnico,
Could you please try to test while using this option -H:ThrowMissingRegistrationErrors= to your native image build command and share your findings with me?
Here's an Example Command:
native-image -H:ThrowMissingRegistrationErrors= -jar your-app.jar

2 weeks ago Hi @selhagani, I have added this option to the build and I see it is correctly taken into account by the maven build logs. The native executable is correctly generated without error. When I start the exe, it works without error or warning on the console and I still can not attach the process in visualvm. I added it to the github project that helps reproducing the problem in case you want to have a look at it : https://github.com/cnico/native-image-maven-demo

16 hours ago Hi, Do you have any news on this ticket?
Describe the issue We use native image to build windows native executables and it works very well. As the project gets bigger we investigate on monitoring of the native image to detect memory leak, cpu usage, etc. So we investigated on the option --enable-monitoring=all (same result with jvmstat or heapdump). The native image build is OK but visualvm does never find the native image processus. I did a simple project to reproduce the problem : https://github.com/cnico/native-image-maven-demo It builds and runs on linux with the correct expectation of visualvm finding the processus. But on windows it finds no processus to attach as native image. It works great for the java -jar execution of course.
Steps to reproduce the issue
Describe GraalVM and your environment:
More details The generated native-image args file seems correct : @target\tmp\native-image-6483500328482094922.args :
Here are the logs of the maven execution of the native image with --native-image-info and --verbose options :
