Steps To Reproduce

  1. create MN app with
curl --location --request GET 'https://launch.micronaut.io/create/default/com.a0d.playground.jtetester.JteTester?lang=JAVA&build=GRADLE&test=SPOCK&javaVersion=JDK_21&features=graalvm&features=views-jte' --output JteTester.zip
  1. Add Controller 
    
package com.a0d.playground.jtetester.controller;

import io.micronaut.core.util.CollectionUtils; import io.micronaut.http.HttpResponse; import io.micronaut.http.annotation.Controller; import io.micronaut.http.annotation.Get; import io.micronaut.views.View;

@Controller public class RootController {

@Get("/")
@View("example")
public HttpResponse<?> index() {
    return HttpResponse.ok(CollectionUtils.mapOf("message", "kuba", "showTime", true));
}

}



3. Create native build.
4. Start native build
5. Browse web app

### Environment Information

- Java version: 21.0.2+13, vendor version: GraalVM CE 21.0.2+13.1
- Graal compiler: optimization level: 2, target machine: armv8-a
- C compiler: cc (apple, arm64, 16.0.0)

### Example Application

It is easier to use Micronaut Launch and add this tiny controller from above.

### Version

4.6.2
kurb70 commented 1 month ago

When I start the app via java, the JTE view is displayed without any problems.

Ooops I've just realised that I mistakenly claimed that I was using version 4.4.2.

But I was using Micronaut 4.6.2. BTW The problem also occurs with 4.6.3
