>   When shared archive (dynamic archive) failed to map due to damage of the archive file, dump/run jdk version mismatch or non-existence file etc, the new patch will automatically create a new shared archive if -XX:+AutoCreateSharedArchive specified with the name based on SharedArchiveFile.
>   This is a revised patch based on the old PR: 5077 and after bug 8273152 integrated.
> 
> Tests: tier1,tier2,tier3,tier4
