> Key: LUCENE-9067
> URL: https://issues.apache.org/jira/browse/LUCENE-9067
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Ignacio Vera
> Priority: Major
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> We hit the following test error:
>
> {code:java}
> ant test -Dtestcase=TestLatLonDocValuesQueries -Dtests.method=testAllLonEqual -Dtests.seed=E5C923927CDBBE49 -Dtests.slow=true -Dtests.badapples=true -Dtests.locale=tr-CY -Dtests.timezone=Etc/GMT-8 -Dtests.asserts=true -Dtests.file.encoding=US-ASCII{code}
>
> The problem is that Polygon2D is not thread safe but Lucene assumes that multiple scorers from the same weight can be consumed concurrently. I that case two threads accessing the contains method on the same polygon can lead to bad answers.
