And, the CaffeineCache has to be set as async. It defaults to async, but I 
added the async=“true” to be explicit in my solrconfig.xml

        <filterCache
            class="solr.CaffeineCache"
            size="5000"
            initialSize="500"
            autowarmCount="100"
            async="true"
            />
