-XX:+AutoCreateSharedArchive is for creating dynamic CDS archives only. 
It cannot be used for creating static CDS archives.

-XX:+AOTLoadedClasses works for both dynamic and static CDS archives. 
However, as part of this JEP, to demonstrate its promises, we will also 
implement one significant optimization that relies on 
-XX:+AOTLoadedClasses:

     JDK-8293336 Store LambdaForms in CDS archive heap

JDK-8293336 works only for the static CDS archive (it requires archiving 
Java heap objects, which is not supported by dynamic CDS archives).

Thanks
