> This is an enhancement of the test case in [JDK-8296754](https://bugs.openjdk.org/browse/JDK-8296754), which tests against an archive created by the "boot JDK", which is usually set as the previous official JDK release when building the JDK repo.
> 
> If it's able to acquire previous valid JDK releases:
>      - Download and install previous JDK versions (19 through N)
>         where N == java.lang.Runtime.version().major() - 1
>      - Test the interaction of the current JDK versus each of the previous releases
> 
> If it's not able to find the previous releases revert to the existing logic in TestAutoCreateSharedArchiveUpgrade.java (use the test.boot.jdk or test.previous.jdk properties). Verified with tier1-4 tests.
