I deployed shield on ES `v1.1.2` but it failed due to `java.lang.NoClassDefFoundError` ... is it _NOT_ meant to be used by ES `v1.1.2`?

```

Shield only works with Elasticsearch 1.4.2 and newer. I would recommend upgrading to Elasticsearch 1.7.1 as it contains a lot of fixes and 1.1.2 is pretty old.
