Warning: annotation processor 'org.apache.openjpa.persistence.meta.AnnotationProcessor6' is less than -source '1.8'

I am getting the warning below from the maven-processor-plugin when used to handle the Open JPA meta-model for Java 8. My project does build, but is there a Java 8 version that doesn't generate this warning? I don't see the Java 8 version of org.apache.openjpa.persistence.meta.AnnotationProcessor6.

warning: Supported original version 'RELEASE_6' from annotation processor 'org.apache.openjpa.persistence.meta.AnnotationProcessor6' is less than -source '1.8'

It ended up working for me using this example:

<plugin>
    <groupId>org.bsc.maven</groupId>
    <artifactId>maven-processor-plugin</artifactId>
    <version>2.1.0</version>
    <executions>
        <execution>
            <id>process</id>
            <goals>
                <goal>process</goal>
            </goals>
            <phase>generate-sources</phase>
            <configuration>
                <compilerArguments>-Aopenjpa.source=8 -Aopenjpa.metamodel=true</compilerArguments>
                <processors>
                    <processor>org.apache.openjpa.persistence.meta.AnnotationProcessor6</processor>
                </processors>
                <outputDirectory>target/generated-sources/metamodel</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>
