Description

Was testing out my new laptop and I hit this reproducing failure:

ERROR: The following test(s) have failed:
  - org.apache.solr.TestRandomDVFaceting.testRandomFaceting (:solr:core)
    Test output: /Users/gus/projects/apache/solr/code/solr/solr/core/build/test-results/test/outputs/OUTPUT-org.apache.solr.TestRandomDVFaceting.txt
    Reproduce with: gradlew :solr:core:test --tests "org.apache.solr.TestRandomDVFaceting.testRandomFaceting" -Ptests.jvms=10 -Ptests.jvmargs=-XX:TieredStopAtLevel=1 -Ptests.seed=D7D46A8DCC1CFDE6 -Ptests.file.encoding=US-ASCII

This might be similar to SOLR-14990 but that issue didn't record a stack trace or error message. For this issue I see

Which might be a lucene level issue anyway, don't have time to properly investigate, but opening this to track.
