> The current logging method FileMapInfo::fail_continue() method reports the reason when the CDS archive cannot be mapped and has variable behavior depending on the -Xshare mode. Logging calls are divided primarily between the "warning" and "info" channels, where the "info" channel was used to reduce the number of printed logs for expected and normal failures.

Some genuine failures will be logged to the warning channel for better visibility. Upon actual failures, the VM will exit at MetaspaceShared::initialize_runtime_shared_and_meta_spaces() unless it is otherwise necessary. Relevant tests are updated to accommodate this change. Verified with tier1-4 tests
