             Summary: Schema API: Can't remove single dynamic copy field directive
                 Key: SOLR-7542
                 URL: https://issues.apache.org/jira/browse/SOLR-7542
             Project: Solr
          Issue Type: Bug
    Affects Versions: 5.1
            Reporter: Steve Rowe
             Fix For: 5.2


In a managed schema containing just a single dynamic copy field directive - i.e. a glob source or destination - deleting the copy field directive fails.  For example, the default configset (data_driven_schema_configs) has such a schema: the {{*}}->{{\_text\_}} copy field directive is the only one. 

To reproduce:

{noformat}
bin/solr start -c
bin/solr create my_solr_coll
curl "http://localhost:8983/solr/my_solr_coll/schema" -d'{"delete-copy-field":{"source":"*", "dest":"_text_"}}'
{noformat}

The deletion fails, and an NPE is logged:
