Error occurs on tests with @Nested classes and QuarkusMainLauncher

[benDeMtp]

Describe the bug

On a quarkus cli app, when tests contains 2 or more nested classes and QuarkusMainLauncher#lauch() is called in a nested classe, tests throws an Error:

@QuarkusMainTest
public class GreetingCommandTest {

    @Test
    void test1(){
        assertTrue(true);
    }

    @Nested
    class Nested1{

        @Test
        void test2(){
            assertTrue(true);
        }
    }

    @Nested
    class Nested2{

        @Test
        void test3(QuarkusMainLauncher launcher){
            LaunchResult result = launcher.launch("-h");
            assertTrue(true);
        }
    }

}

The error occurs when there is :

• 2 Nested classes or more
• launcher.launch() called in a nested class

There is no error if :

• there is only one nested class,
• or if launcher.launch() is not called in an nested class.
