Hi, I got following warnings, when running elasticsearch on arm platform: ``` [2017-10-06T18:10:08,825][WARN][o.e.b.Natives] unable to load JNA native support library, native methods will be disabled.

Will them degrade performance? Any Idea how I can get JNA running on arm? Thanks, Andreas ---

The warning is not critical. However, note that 32 bit support is [removed in 6.0](https://github.com/elastic/elasticsearch/pull/25435). The jna lib is shipped with aarch64 support though (although there is no official support for Elasticsearch on any arm, 32 or 64 bit). ---
