Description

(NOTE: I noticed this while working on a test for type: range but it's possible other facet types may be affected as well)

When dealing with a single core request – either standalone or a collection with only one shard – json.facet seems to use "Integer" objects to return the "count" of facet buckets, however if the shard count is increased then the end client gets a "Long" object for the "count"

(This isn't noticable when using wt=json but can be very problematic when trying to write client code using wt=xml or SolrJ
