Summary

• Problem happens because Cloud instance shows filesize-0 from the issue page.
• Attachment affected by this problem will also shows filesize=0 in Cloud instance's fileattachment table.
• Since the value of the filesize is saved as 0 in database, the filesize will be saved as 0 in entites.xml generated for JIRA Server migration.
