2.4.0 upgrade generate error when trying to process our existing mappings:

java.lang.IllegalArgumentException: Cannot set position_increment_gap on field [all_near_match] without positions enabled

This can be traced to a fix merged in v2.4.0.

Elasticsearch 2.4.0 has a bug that prevents us from upgrading. We will analyze the next release when available to see if we upgrade to it. In the meantime, nothing more is needed on 2.4.0, we will not upgrade to this version.
