Re: [jakartaee-platform-dev] Proposed language to drop BMP and CMP in th

This change is very much appreciated and welcomed. 

In my opinion CMP and BMP should have been removed as platform requirements a long time ago (it should actually never have been included, but that's another discussion ;))

In the Platform Specification, I find that EJB CMP and BMP are only mentioned in section 12.2.1, Jakarta Persistence. The entire text of that section is:

12.2.1. Jakarta Persistence

Jakarta Persistence provides a much richer set of modeling capabilities and object/relational mapping capabilities than EJB CMP entity beans and is significantly easier to use.

Support for EJB CMP and BMP entity beans has been made optional with the Java EE 7 release. Support for EJB CMP 1.1 entity beans has been optional since Java EE 5. Applications are strongly encouraged to migrate applications using EJB entity beans to Jakarta Persistence.

As we had previously discussed dropping requirements in CMP and BMT, but this not implemented, I propose the text be modified as following:

12.2.1. Jakarta Persistence

Jakarta Persistence provides a much richer set of modeling capabilities and object/relational mapping capabilities than EJB CMP entity beans and is significantly easier to use.

Support for Jakarta EJB CMP was made optional in Java EE 5 and BMP was made optional in Java EE 7. In Java EE 10, these persistence modes are no longer required by the platform. Compatible products may continue to support these persistence modes in Jakarta EE 10. Compatible products supporting Enterprise Java Beans CMP and BMP must meet the requirements described in the Enterprise Java Beans specification for CMP and BMP and pass the appropriate compatibility tests included in the Jakarta EE 10 Platform TCK. These tests are supported in the Jakarta EE 10 Platform TCK. Enterprise Java Beans, CMP and BMP will be deprecated for removal in a future release.

GlassFish does currently support these modes, and it is my hope that this will allow us to maintain the feature for products that wish to continue using it -- announce the deprecation (hopefully in EE 11) -- and finally allow us to certify compatible implementations that do not include support for BMP and CMP.  No changes would be made to the EJB specification and the feature still exists and is defined by the component specification. We're just removing the Platform requirement.

If there is general agreement in this direction, I could start a PR to begin our discussion on this text. If someone else would like to pick this up, I'm happy to step back or put this on hold for EE 11.
