Description

Requesting /solr/admin/file/?contentType=text/xml;charset=utf-8&file=schema.xml generates an HTTP 500:

It's not related to a specific file, requesting /solr/admin/file is enough.

• is duplicated by: SOLR-2979 ShowFileRequestHandler should really also work with config files in ZooKeeper - our UI relies on it to see the solrconfig and schema.
