------------------------------------
Summary: TestGroupFacetCollector#testRandom has caught
IndexOutOfBoundsException a couple times
Key: LUCENE-10595
URL: https://issues.apache.org/jira/browse/LUCENE-10595
Project: Lucene - Core
Issue Type: Bug
Components: modules/grouping
Reporter: Greg Miller
Random testing has caught an {{IndexOutOfBoundsException}} a couple times now
in {{org.apache.lucene.search.grouping.TestGroupFacetCollector.testRandom}}. I
was able to reproduce locally with {{./gradlew :lucene:grouping:test --tests
"org.apache.lucene.search.grouping.TestGroupFacetCollector.testRandom"
-Ptests.jvms=4 -Ptests.haltonfailure=false
-Ptests.jvmargs=-XX:TieredStopAtLevel=1 -Ptests.seed=91EC8BE9DE2A5BAB
-Ptests.multiplier=2 -Ptests.badapples=false -Ptests.file.encoding=US-ASCII}}.
>From what I can tell, the exception is coming from way down in
>{{ByteBuffersDataInput#readBytes}} on [this
>line|https://github.com/apache/lucene/blob/main/lucene/core/src/java/org/apache/lucene/store/ByteBuffersDataInput.java#L155].
> Popping the stack a bit, it seems like the issue is maybe in
>{{TermGroupFacetCollector$MV$SegmentResult#nextTerm}}.
I'm not totally sure if this is an actual bug or a bug in testing methodology.
Haven't had time to dig in further and likely won't in the near future, so
opening this Jira to track.
