[CI] reindex oldEs090Fixture failure (no useful log info)

[tvernum]

The task for oldEs090Fixture failed (7.6, darwin, see output below) but I can't tell why ant/gradle decided that it failed. The gradle log lacks anything that makes sense to me, and there's nothing reindex related in the google cloud storage bundle.
