Strange issue with TomEE 8.0.4 and OpenApi extension (Swagger-UI 1.0.3)

Question

I'm using TomEE microprofile and have defined my rest application path this way:

 @ApplicationPath("api")
 public class RestConfiguration extends Application {

 }

When the application is deployed, tomee log shows the access url to the generated front end resources:

 Service URI: http://localhost:8080/api/openapi-ui/
 

When accesing the url got this message in the swagger-ui web page:

Fetch error undefined /openapi

If I change the application path to empty:

 @ApplicationPath("")

Then all works fine and swagger shows all of the service method definitions.

So, what should I do to make it work adding "api" to the ApplicationPath annotation?

Tried with "/api", but doesn't work either.

I made the test here with Tomee-8.0.4, follow the configurations, assumed that you that is using a JAR.

in your pom.xml use the dependency:

    <dependency>
        <groupId>org.microprofile-ext.openapi-ext</groupId>
        <artifactId>openapi-ui</artifactId>
        <version>1.1.3</version>
    </dependency>

 <build>
        <finalName>tomee-demo</finalName>
        <plugins>
            <plugin>
                <groupId>org.apache.tomee.maven</groupId>
                <artifactId>tomee-maven-plugin</artifactId>
                <version>${tomee.version}</version>
                <executions>
                    <execution>
                        <id>executable-jar</id>
                        <phase>package</phase>
                        <goals>
                            <goal>exec</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <context>ROOT</context>
                    <tomeeClassifier>microprofile</tomeeClassifier>
                </configuration>
            </plugin>
        </plugins>
    </build>

in microprofile-config.properties use:

mp.openapi.servers=http://localhost:8080/api
openapi.ui.yamlUrl=/api/openapi
openapi.ui.serverVisibility=visible

and run your project again.
