Mismatch between release.version in pom.xml and dependencies

[lutzh]

Hi, I'm trying to compile the master branch of the project and one of the difficulties I'm facing is:

In the parent pom.xml, release.version that is used for the target and release compiler flags is set to 8 in line 65:

<release.target>8</release.target>
But there's a dependency in the parallel-consumer-mutiny module:

        <dependency>
            <groupId>io.smallrye.reactive</groupId>
            <artifactId>mutiny</artifactId>
            <version>2.9.4</version>
        </dependency>

that uses java.util.concurrent.Flow and other classes that where only introduced in Java 9. In fact, I think the compiler target for that dependency is 17.

Are there instructions on how to compile the project? There must be some tricks, I don't see how this can work for anyone.
