             Summary: Highlighting grouped duplicate docs from different shards with group.limit > 1 throws ArrayIndexOutOfBoundsException
                 Key: SOLR-5709
                 URL: https://issues.apache.org/jira/browse/SOLR-5709
             Project: Solr
          Issue Type: Bug
          Components: highlighter
    Affects Versions: 4.6, 4.5, 4.4, 4.3, 5.0
            Reporter: Steve Rowe
            Assignee: Steve Rowe


In a sharded (non-SolrCloud) deployment, if you index a document with the same unique key value into more than one shard, and then try to highlight grouped docs with more than one doc per group, where the grouped docs contain at least one duplicate doc pair, you get an AIOOB.

Here's the stack trace I got from such a situation, with 1 doc indexed into each shard in a 2-shard index, with {{group.limit=2}}:
