> ShardSplitTest 100% failures on main branch

> Key: SOLR-17360
> URL: https://issues.apache.org/jira/browse/SOLR-17360
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Chris M. Hostetter
> Priority: Major
>
> ShardSplitTest is a nightly only testclass that has 4 test methods which have
> recently been failing 100% of the time in jenkins, regardless of seed...
> * testSplitMixedReplicaTypes
> * testSplitStaticIndexReplicationLink
> * testSplitStaticIndexReplication
> * testSplitMixedReplicaTypesLink
>
> ...but AFAICT these failures are not new. IIUC this test has been failing on
> 100% of – the _MAIN_ branch – jenkins builds since ~ Oct/Nov {*}2023{*}!
> (I believe the historical graphs since then just look "sporadic" because it's
> a nightly only test so run's very infrequently and was still (mostly) passing
> on the 9x branch)
>
> ----
>
> It's trivial to see these failures locally, regardless of seed; or whether
> you run a single test method, or multiple test methods.
> Example...
> {noformat}
> git clean -fd && ./gradlew -p solr/core test -Ptests.nightly=true --tests
> ShardSplitTest.testSplitMixedReplicaTypes{noformat}
