getResource with absolute resource name is not working in native image

Describe the bug Absolute resource names are not found in native images (with beginning ‘/’)

Expected behavior Absolute resource names should be found

To Reproduce Steps to reproduce the behavior:

Create any Jax-rs resource and add a property file.

@Path("jobs")
@ApplicationScoped
public class JobResource {

    @GET
    @Path("/simple-job")
    @Produces(MediaType.APPLICATION_JSON)
    public SimpleResponse simpleJob(@DefaultValue("World") @QueryParam("name") String name) throws IOException {
        final ClassLoader contextClassLoader = Thread.currentThread().getContextClassLoader();
        String propteryFile = "/org/jobrunr/examples/webapp/api/test.properties";
        final URL resource1 = contextClassLoader.getResource(propteryFile);
        System.out.println("Property file exists: " + (resource1 != null));

        String propteryFile2 = "org/jobrunr/examples/webapp/api/test.properties";
        final URL resource2 = contextClassLoader.getResource(propteryFile2);
        System.out.println("Property file exists: " + (resource2 != null));

        return new SimpleResponse("Job Enqueued");
    }
}

In JVM mode the output is as follows: Property file exists: true Property file exists: true

In native mode the output is as follows: Property file exists: false Property file exists: true

Unless I don’t understand the spec correctly, I think resources with beginning ‘/’ should be handled as absolute resources: https://docs.oracle.com/javase/8/docs/api/java/lang/Class.html#getResource-java.lang.String-

Yeah, we should address that

[rdehuyss]

Yes - my mistake - doing further testing to find root cause.
