Hi Default response in Solr 7 is now JSON instead of XML (https://issues.apache.org/jira/browse/SOLR-10494)
We are using a system that use the Solr admin/cores api for core status etc. and we can't really change that system. That system expects the XML response. And as far as I can see default also changed to JSON there. So: Are there any way I can change the admin/cores API back to responses using XML instead of JSON? /Roland Villemoes
