nonFinal, do we still need it?

The plug-in uses a convention for something called "nonFinal", which I think didn't carry over to Jakarta:

e.g.

```
// OSGi Bundle-SymbolicName: ${API_PACKAGE}-api
// OSGi bundle specversion: ${SPEC_VERSION}.99.b${SPEC_BUILD}
// OSGi Bundle-Version: ${SPEC_VERSION}.99.b${SPEC_BUILD}
// jar Extension-Name: ${API_PACKAGE}
// jar Specification-Version: ${SPEC_VERSION}.99.${SPEC_BUILD}
// jar Implementation-Version: ${NEW_SPEC_VERSION}-b${SPEC_BUILD}
```

Do we need to retain this?

Start by reviewing the glassfish-spec-version-maven-plugin code that generates the OSGi and JAR version metadata shown in the issue, and trace how the nonFinal convention is handled. Done means establishing whether Jakarta still requires these values and documenting a decided removal or retention path.
