Building the Quarkus extension fails with:

[WARNING] Rule 2: org.apache.maven.plugins.enforcer.BannedDependencies failed with message:
Found Banned Dependency: org.jboss.spec.javax.annotation:jboss-annotations-api_1.2_spec:jar:1.0.0.Final

This spec jar is brought in as a transitive dependency in this dependency chain: optaplanner-core >> drools-model-compiler >> drools-mvel-parser >> jboss-annotations-api_1.2_spec, where (>> means depends on).

Since Quarkus bans the jboss-annotations-api spec jar, an alternative is needed to replace it.
