How can one reproduce the bug?

REPRODUCE WITH: ./gradlew ':integTest' --tests "org.opensearch.geospatial.search.aggregations.bucket.geogrid.GeoHexAggregationIT.testGeoHexGridBucket" -Dtests.seed=9906CEDA8615A7A5 -Dtests.security.manager=false -Dtests.locale=mk -Dtests.timezone=Asia/Atyrau -Druntime.java=17

What is the expected behavior? Pass the test
