Since JDK-8348426, the AOTConfiguration file format is changed from a text file into a binary file. The resolved Class/Field/Method constant pool entries are missing from the config file.

In the follow example, you can see the number of resolved classes and methods are significantly lower in the "AOT workflow vs the classical "CDS" workflow:

AOT
Class CP entries = 35502, archived = 5974 ( 16.8%), reverted = 0
Method CP entries = 6650, archived = 6632 ( 99.7%), reverted = 18

CDS
Class CP entries = 35102, archived = 10392 ( 29.6%), reverted = 0
Method CP entries = 10551, archived = 10527 ( 99.8%), reverted = 24
