Chris M. Hostetter commented on SOLR-18188:
-------------------------------------------
git bisect has identified this issue as the root cause of some reproducible
jenkins failures from {{ForceLeaderTest.testReplicasInLowerTerms}} that seem to
happen on both main and 10x.
(Presumably it's also the cause of a similar increase in failures in
{{ForceLeaderWithTlogReplicasTest.testReplicasInLowerTerms}} )
Sample seed from main...

./gradlew -p solr/core test --tests ForceLeaderTest.testReplicasInLowerTerms

> solr-test-framework: Remove Apache HttpClient usages
> ----------------------------------------------------
>
> Key: SOLR-18188
> URL: https://issues.apache.org/jira/browse/SOLR-18188
> Project: Solr
> Issue Type: Task
> Components: test-framework, Tests
> Reporter: David Smiley
> Assignee: David Smiley
> Priority: Major
> Labels: pull-request-available
> Fix For: 10.1
>
> Time Spent: 6h 50m
> Remaining Estimate: 0h
>
> As of this writing, the last usages of Apache HttpClient are in Solr's tests.
> This issue aims to remove it completely. But it's a lot of work.
> Some possible steps:
> * Remove tests for our HttpSolrClient & friends (fundamentally based on
> Apache HttpClient)
> * Replace usages of HttpSolrClient.getHttpClient with
> HttpJettySolrClient.getHttpClient
> * Replace usages of HttpSolrClient.getBaseURL by introducing a new base
> client that has this method. Or access similarly from Jetty when easily
> available.
> * of course, stop using HttpSolrClient & friends. Maybe class-by-class.
