Jan Høydahl commented on SOLR-15856:
------------------------------------
This keeps failing with a 9% failure rate. Did we conclude whether this might
be a Lucene bug or not?
[~magibney] 's seed above reproduces consistently on my Mac running {{OpenJDK
Runtime Environment Temurin-11.0.14+9 (build 11.0.14+9)}}
Even without the {{tests.jvmargs}} the seed {{AAD40B94A69376B2}} seems to
trigger the index out of bounds:
{code:java}
gradlew :solr:core:test --tests
"org.apache.solr.TestRandomDVFaceting.testRandomFaceting"
-Ptests.seed=AAD40B94A69376B2{code}
