Description

When querying for collection status, a null pointer exception is returned. I believe it is caused by the use of "implicit" routing for the shards and the Admin Handler trying to set the "Range" attribute of a shard (when one doesn't exist).

// org.apache.solr.handler.admin.ColStatus.getColStatus(ColStatus.java:152)
sliceMap.add("range", s.getRange().toString());

I believe "getRange()" is NULL since implicit routing is used.
