-----------------------------------------

             Summary: json.facets: allBucket:true can cause server errors when combined with refine:true
                 Key: SOLR-14520
                 URL: https://issues.apache.org/jira/browse/SOLR-14520
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
          Components: Facet Module
            Reporter: Chris M. Hostetter


Another bug that was discovered while testing SOLR-14467...
In some situations, using {{allBuckets:true}} in conjunction with {{refine:true}} can cause server errors during the "refinement" requests to the individual shards -- either NullPointerExceptions from some (nested) SlotAccs when SpecialSlotAcc tries to collect them, or ArrayIndexOutOfBoundsException from CountSlotArrAcc.incrementCount because it's asked to collect to "large" slot# values even though it's been initialized with a size of '1'

NOTE: these problems may be specific to FacetFieldProcessorByArrayDV - i have not yet seen similar failures from FacetFieldProcessorByArrayUIF (those are the only 2 used when doing refinement) but that may just be a fluke of testing.
