Description

HEAD requests for managed stopwords/synonyms fail with 500 Server Error. This is true for both stopword lists/synonym maps and their child resources.

$ curl -sI "http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english" | head -n 1
HTTP/1.1 500 Server Error

$ curl -sI "http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english/happy" | head -n 1
HTTP/1.1 500 Server Error

A request for a non-existent word in a list/map does return the correct 404 response.

$ curl -sI "http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english/unhappy" | head -n 1
HTTP/1.1 404 Not Found
