Managed Beans spec used to be under Web Profile. In Jakarta EE 10, this spec was indeed removed from Jakarta EE 10 Web Profile spec. <https://jakarta.ee/specifications/webprofile/10/jakarta-webprofile-spec-10.0.html> However, it was still listed under the Jakarta EE 10 Web Profile release in this <https://jakarta.ee/release/10/> diagram. The diagram needs to be updated to reflect the current status.

Could someone more familiar with this confirm what this means for the 
Servlet specification.

Do we just need to remove the one reference to the managed bean 
specification from the Servlet spec doc?

The reference to @PostConstruct below concerns me. Is there any 
expectation that removing the Managed Bean spec will have any impact on 
section 15.5 of the Servlet specification (Annotations and Resource 
Injection)?

Thanks,

Mark
