Description

Performing the apache-release deploy in JDK16 results in the javadoc plugin failing with issues related to the module path.

Hopefully the fix is to update from javaee-api 8:0 to jakarta ee 8.0 (see commit `5be630aeb2cf82d34abb0eb380b8bf49674edb8f` for a first cut on this, aborted), and then also author the module-info.java classes for each (maven) module.
