Major Description
Copy field delete statements for the Schema API are not working when the source field contains an underscore (havent tested this for "dest") . If the underscore is removed deletion is working as intended. Another user of Solr seems to have had the same problem and was asked to create a Jira ticket. I can however not find this ticket anywhere hence this ticket.

I upgraded to the newest version and the problem still persists.
It should be simple to reproduce. Just include and underscore in a copy field statement in your schema file and try to delete the copy field using the api, as seen below:
