[BUG] OperationRoutingTests.testWeightedOperationRoutingWeightUndefinedForOneZone failure

[andrross]

Failure here: https://build.ci.opensearch.org/job/gradle-check/5293/

This test failure appears to be reproducible with the given seed:

./gradlew ':server:test' --tests "org.opensearch.cluster.routing.OperationRoutingTests.testWeightedOperationRoutingWeightUndefinedForOneZone" -Dtests.seed=B1745FEE14F29C02 -Dtests.security.manager=true -Dtests.jvm.argline="-XX:TieredStopAtLevel=1 -XX:ReservedCodeCacheSize=64m" -Dtests.locale=ar-EG -Dtests.timezone=Asia/Magadan -Druntime.java=17

I haven't investigated at all but should be easily fixable given that it is deterministic.

Maybe not a one-off...another failure here: https://build.ci.opensearch.org/job/gradle-check/5299/

I've submitted #4980 as an attempt to fix this issue. I've observed that there are different behaviors when using java17 specially with those related to math,
