In that call, we discussed an approach where Jakarta EE 12 could effectively use MicroProfile Config "as is" with some important non-technical accommodations.
- 
The APIs for Jakarta Config would be the MicroProfile Config APIs, but with jakarta namespace. Yes, a copy/paste.
- 
The implementation may delegate to the MicroProfile Config implementation.
- 
The Spec document would be one-line: see the corresponding MicroProfile config spec document.  May need additional text to talk about the difference in namespace and adding in jakarta-config.properties until a new MP Config version added that to its specification. 
 See #5 below.
- 
The TCK would be a copy/paste of the MicroProfile Config TCK and updating the name space and adding jakarta-config.properties testing
- 
Need to introduce a new line in the 
ConfigSource
 (MicroProfile Config API)
- 
“Some configuration sources are known as default configuration sources. These configuration sources are normally available in all automatically-created configurations, and can be manually added to manually-created configurations as well. The default configuration
 sources are:
- 
1. System properties, with an ordinal value of 400
- 
2. Environment properties, with an ordinal value of 300
- 
3. The /META-INF/jakarta-config.properties resource, with an ordinal value of 200
- 
4. The /META-INF/microprofile-config.properties resource, with an ordinal value of 100
Let's continue discussion using this "both lists on the To: line" approach rather than introduce another venue, such as the cn4j
mailing
 list (
eclipse
 archive).
