In native mode a static instance cannot load resources as the resource URL references a jar in the path

Describe the bug

When an object is instantiated as static then the object or any objects instantiated by it are not able to load resources.

If I instantiate the object as non static, then when the object tries to load a resource, the resource URL looks like this:

resource:/diagram-interchange-dish-example.dmn

If I instantiate the same object as static, then the resource URL looks like this:

jar:file:/project/quarkus-bug-1.0-SNAPSHOT-runner.jar!/diagram-interchange-dish-example.dmn

This is the exception I get when I try to open a resource loaded by a static object:

Expected behavior

the resource URL is the same for both scenarios (static and non static resource loader objects)

resource:/diagram-interchange-dish-example.dmn

Actual behavior

when the object which loads the resource is instantiated as static then the resource URL references a non-existent jar file:

jar:file:/project/quarkus-bug-1.0-SNAPSHOT-runner.jar!/diagram-interchange-dish-example.dmn

How to Reproduce?

Link to a minimal project to reproduce the issue: https://drive.google.com/file/d/1ZeIZypM1rCpA0SVsUW33uwi2hV1GlntF/view?usp=sharing

build it with

mvn clean install -Pnative

sample code:

‘’’ public class QuarkusBug implements RequestHandler<Map<String, Object>, Map<String, Object>> {

@Slf4j public static class Loader { private URL resource;

public Loader() {
  resource = Loader.class.getClassLoader().getResource("diagram-interchange-dish-example.dmn");
  log.info("-------------- LOADER CONSTRUCTOR: {}", resource);
}

public void loader() {
  resource = Loader.class.getClassLoader().getResource("diagram-interchange-dish-example.dmn");
  log.info("-------------- LOADER METHOD: {}", resource);
}

public void read() {
  log.info("-------------- LOADER READ RESOURCE: {}", resource);
  try (InputStream is = resource.openStream()) {
    log.info("-------------- LOADER READ OPERATION: {}", new String(is.readNBytes(38)));
  } catch (IOException e) {
    throw new RuntimeException(e);
  }
}

}

// THE FAILING ONE private static Loader loader = new Loader();

// THE PASSING ONE // private Loader loader = new Loader();

public QuarkusBug() { loader.read(); }

@Override public Map<String, Object> handleRequest(Map<String, Object> request, Context context) { return request; } } ‘’’
