Relevant tests

Code branches for getLeafCollector() should result in only one possible value > 0. Two test cases are for each type

test_1:

OpenSearch/rest-api-spec/src/main/resources/rest-api-spec/test/search.aggregation/20_terms.yml

Lines 856 to 857 in ea1cc9d

- gt: { profile.shards.0.aggregations.0.debug.segments_with_single_valued_ords: 0 }
- match: { profile.shards.0.aggregations.0.debug.segments_with_multi_valued_ords: 0 }

test_3:

OpenSearch/rest-api-spec/src/main/resources/rest-api-spec/test/search.aggregation/20_terms.yml

Lines 907 to 908 in ea1cc9d

- match: { profile.shards.0.aggregations.0.debug.segments_with_single_valued_ords: 0 }
- gt: { profile.shards.0.aggregations.0.debug.segments_with_multi_valued_ords: 0 }

However, stash dump shows both have a value of 1:

  1>                 "debug" : {
  1>                   "segments_with_multi_valued_ords" : 1,
  1>                   "collection_strategy" : "dense",
  1>                   "segments_with_single_valued_ords" : 1,
  1>                   "deferred_aggregators" : [
  1>                     "max_number"
  1>                   ],
  1>                   "result_strategy" : "terms",
  1>                   "has_filter" : false
  1>                 },

The max aggregator shows it has built two leaf collectors:

  1>                 "children" : [
  1>                   {
  1>                     "type" : "MaxAggregator",
  1>                     "description" : "max_number",
  1>                     "time_in_nanos" : 166539,
  1>                     "breakdown" : {
  1>                       "reduce" : 0,
  1>                       "post_collection_count" : 1,
  1>                       "build_leaf_collector" : 104055,
  1>                       "build_aggregation" : 12091,
  1>                       "build_aggregation_count" : 1,
  1>                       "build_leaf_collector_count" : 2,
  1>                       "post_collection" : 1241,
  1>                       "initialize" : 6207,
  1>                       "initialize_count" : 1,
  1>                       "reduce_count" : 0,
  1>                       "collect" : 42945,
  1>                       "collect_count" : 4
  1>                     }
  1>                   }
  1>                 ]

Superclass variables are protected, it's possible they are not reset between the collections.
