Iurii Vyshnevskyi created LUCENE-9580:
-----------------------------------------
Summary: Tessellator failure for a certain polygon
Key: LUCENE-9580
URL: https://issues.apache.org/jira/browse/LUCENE-9580
Project: Lucene - Core
Issue Type: Bug
Affects Versions: 8.6, 8.5
Reporter: Iurii Vyshnevskyi
This bug was discovered while using ElasticSearch (checked with versions 7.6.2
and 7.9.2).
But I've created an isolated test case just for Lucene:
[https://github.com/apache/lucene-solr/pull/2006/files]
The unit test fails with "java.lang.IllegalArgumentException: Unable to
Tessellate shape".
The polygon contains two holes that share the same vertex and one more
standalone hole.
Removing any of them makes the unit test pass.
Changing the least significant digit in any coordinate of the "common vertex"
in any of two first holes, so that these vertices become different in each hole
- also makes unit test pass.
