We have integration tests that allow us to validate the behavior of mapping generation. They are executed automatically, but I just ran them to be sure, and (at least in those tests), analyzer references are present in the generated mapping:

  "tweet" : {
    "mappings" : {
      "org.hibernate.search.elasticsearch.test.ElasticsearchAnalyzerIT$Tweet" : {
        "dynamic" : "strict",
        "properties" : {
          "customTweet" : {
            "type" : "string",
            "analyzer" : "custom-analyzer"
          },
          "englishTweet" : {
            "type" : "string",
            "analyzer" : "english"
          },
          "tweetNotAnalyzed" : {
            "type" : "string",
            "index" : "not_analyzed",
            "store" : true
          },
          "tweetWithCustom" : {
            "type" : "string",
            "analyzer" : "custom-analyzer"
          },
          "whitespaceTweet" : {
            "type" : "string",
            "analyzer" : "whitespace"
          }
        }
      }
    }
  }

This means that this problem is not a general one, but happens in a specific setup. I am unfortunately unable to guess how in the world this could happen, so a test case would help.
Do you thing you could provide one? Test case templates are available here.
Alternatively, are there any errors or stack traces in your logs?
