Change: This destructive operation should not happen in method the AzureArchiveManage.listArchives() which indicates a read-only operation. One option is to pull out this functionality and call it somewhere else.
Why is this an issue? There is a recovery option in org.apache.jackrabbit.oak.segment.file.tar.TarReader#collectFileEntries which calls org.apache.jackrabbit.oak.segment.file.tar.TarReader#backupSafely. If the recovery is run concurrently with AzureArchiveManage.listArchives() the result can be unexpected.
