How to build native image with swing?

[lcy-1024]

run command go get "native-image-agent-final-config" files,but get "java.awt.HeadlessException"

main code:
java.awt.EventQueue.invokeLater(() -> new NewJFrame().setVisible(true));

build:
mvnw verify -DskipITs=false -Dquarkus.test.integration-test-profile=test-with-native-agent

auto generate podman command:

podman run --name quarkus-integration-test-EHvXd -i --rm -p 8081:8081 -p 8444:8444 --entrypoint java -v /d/work/project/xxx/ta
rget:/project:z --env QUARKUS_LOG_CATEGORY__IO_QUARKUS__LEVEL=INFO --env QUARKUS_HTTP_PORT=8081 --env QUARKUS_HTTP_SSL_PORT=8444 --env TEST_URL=http://localhost:8081 --env QUARKUS_PROFILE=test-with-native-agent --env QUARKUS_TES

build failed,the logs is "quarkus.log":

actually it generate json files
native-image-agent-final-config

and then I go on build:
mvnw verify -Dnative -Dquarkus.native.agent-configuration-apply

auto generate build cmd is:

failed output:

Error: An object of type 'sun.nio.ch.FileChannelImpl' was found in the image heap. This type, however, is marked for initialization at image run time for the following reason: classes are initialized at run time by default.
This is not allowed for correctness reasons: All objects that are stored in the image heap must be initialized at build time.

You now have two options to resolve this:

1. If it is intended that objects of type 'sun.nio.ch.FileChannelImpl' are persisted in the image heap, add

   '--initialize-at-build-time=sun.nio.ch.FileChannelImpl'

to the native-image arguments. Note that initializing new types can store additional objects to the heap. It is advised to check the static fields of 'sun.nio.ch.FileChannelImpl' to see if they are safe for build-time initialization, and that they do not contain any sensitive data that should not become part of the image.

2. If these objects should not be stored in the image heap, you can use

   '--trace-object-instantiation=sun.nio.ch.FileChannelImpl'

to find classes that instantiate these objects. Once you found such a class, you can mark it explicitly for run time initialization with

'--initialize-at-run-time=<culprit>'

to prevent the instantiation of the object.

If you are seeing this message after enabling '--strict-image-heap', this means that some objects ended up in the image heap without their type being marked with --initialize-at-build-time.
To fix this, include '--initialize-at-build-time=sun.nio.ch.FileChannelImpl' in your configuration. If the classes do not originate from your code, it is advised to update all library or framework dependencies to the latest version before addressing this error.
Please address this problem to be prepared for future releases of GraalVM.

Hello @lcy-1024, there is no plan to support desktop integration with Quarkus Native at the moment, left alone whole Swing toolkit. All our image processing, graphics etc. endeavors revolve around headless usage, i.e. server side rendering, documents processing, documents conversions etc.

Could you share what is the use case you would like to solve? What is it you need the app to do for the user?

[lcy-1024]

Hi Karm, a native image can't be decompile,it's more safer, and don't need run with JRE so that it's more convenient and faster.Java have desktop app ability(swing or javafx),why not try to make a java native image desktop app:)

@lcy-1024
Decompilation:
Native-image is easily decompiled, for convenience you can use Ghirda or paid IDA Pro (no experience with that one); Frida scripts also work. We do not attempt any assembly obfuscation or anti-analysis or anti-sandbox tricks. If you hide a proprietary knowledge in the executable it is going to be discovered. The fact that you don't get Java bytecode back does not help to hide much.
Please, do not assume a native-image compilation of a Java program protects your secrets in any way.

Faster:
Yes, the app would have a faster satrtup-time, a rich GUI app would be very specific in how much you have to init at runtime anyway, so the benefit depends... You'd have to measure that.

No JRE:
Yes, sharing a single executable and a handful of .so (.dll/.lib) files is definitely convenient.

Let me close this question as it is not Quarkus related.
