The current 6.0.1-SNAPSHOT narayana-jta installed pom is missing jboss-transaction-spi. I think it could be related to introduce the narayan-bom recently. The jboss-transaction-spi in narayana-bom is marked as "provieded". And the maven-shade-plugin rewrite the pom.xml as dependency-reduced-pom.xml which excludes jboss-transaction-spi artifact.

This casues the quarkus-narayana-jta build failing and missing the classes from "org.jboss.tm" package.
