> Reproducible failure for DirectUpdateHandlerTest
> ------------------------------------------------
>
> Key: SOLR-14784
> URL: https://issues.apache.org/jira/browse/SOLR-14784
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)

> This is rather weird. It apparently was introduced by LUCENE-9456, but that
> seems odd. Although I do note that that push may do some different error
> handling, perhaps Solr needs to accommodate that.
> Of course it doesn't necessarily reproduce with other seeds.
> [~jpountz] do you have any hints?
> Reproduce 100% with:
> ./gradlew :solr:core:test --tests
> "org.apache.solr.update.DirectUpdateHandlerTest"
> -Ptests.seed=2BE3A8682E5E346D -Ptests.multiplier=2 -Ptests.badapples=false
> -Ptests.file.encoding=US-ASCII
