I've run into this error twice now, both on my development laptop and my test server.
Steps to reproduce:
Install an Elasticsearch server.
Install Drupal with search_api, search_api_elasticsearch, search_api_elasticsearch_elastica, the Elastica library, and any required dependencies. Do not install search_api_spellcheck.
Set up a Search API server that connects to the new Elasticsearch server via Elastica.
Set up a Search API index that uses the new server. I gave mine basic configuration like indexing node titles of a particular bundle, but nothing else.
Visit the new index's View page.
Expected behavior:
I should be able to view the index's details.
Actual behavior:
WSOD caused by a PHP fatal error. The stack trace is pasted below. Drupal's class autoloader tries to find the SearchAPISpellcheck class for some reason. Since that module isn't installed, we get a WSOD.
I checked search_api_solr as another example of a Search API module, but it also has its SearchAPISpellcheck subclass being autoloaded. So I don't know why Drupal is trying to autoload the Elasticsearch module's class.
