[DaveCTurner]

This build (https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+master+multijob-unix-compatibility/os=fedora-29&&immutable/655/) failed as follows:

The REPRODUCE WITH line was as follows:

REPRODUCE WITH: ./gradlew ':docs:integTestRunner' --tests "org.elasticsearch.smoketest.DocsClientYamlTestSuiteIT.test {yaml=reference/search/suggesters/misc/line_10}" \
  -Dtests.seed=12A16F45234AB3D2 \
  -Dtests.security.manager=true \
  -Dtests.locale=ja-JP \
  -Dtests.timezone=America/Dawson \
  -Dcompiler.java=13

This did reproduce the failure the first time I tried it.
