> Key: SOLR-13199
> URL: https://issues.apache.org/jira/browse/SOLR-13199
> Project: Solr
> Issue Type: Bug
> Components: search
> Affects Versions: master (9.0)
> Environment: h1. Steps to reproduce
> * Use a Linux machine.
> * Build commit {{ea2c8ba}} of Solr as described in the section below.
> * Build the films collection as described below.
> * Start the server using the command {{./bin/solr start -f -p 8983 -s
> /tmp/home}}
> * Request the URL given in the bug description.
> h1. Compiling the server
> {noformat}
> git clone https://github.com/apache/lucene-solr
> cd lucene-solr
> git checkout ea2c8ba
> ant compile
> cd solr
> ant server
> {noformat}
> h1. Building the collection
> We followed [Exercise
> 2|http://lucene.apache.org/solr/guide/7_5/solr-tutorial.html#exercise-2] from
> the [Solr
> Tutorial|http://lucene.apache.org/solr/guide/7_5/solr-tutorial.html]. The
> attached file ({{home.zip}}) gives the contents of folder {{/tmp/home}} that
> you will obtain by following the steps below:
> {noformat}
> mkdir -p /tmp/home
> echo '<?xml version="1.0" encoding="UTF-8" ?><solr></solr>' >
> /tmp/home/solr.xml
> {noformat}
> In one terminal start a Solr instance in foreground:
> {noformat}
> ./bin/solr start -f -p 8983 -s /tmp/home
> {noformat}
> In another terminal, create a collection of movies, with no shards and no
> replication, and initialize it:
> {noformat}
> bin/solr create -c films
> curl -X POST -H 'Content-type:application/json' --data-binary '{"add-field":
> {"name":"name", "type":"text_general", "multiValued":false, "stored":true}}'
> http://localhost:8983/solr/films/schema
> curl -X POST -H 'Content-type:application/json' --data-binary
> '{"add-copy-field" : {"source":"*","dest":"_text_"}}'
> http://localhost:8983/solr/films/schema
> ./bin/post -c films example/films/films.json
> {noformat}

> Requesting the following URL causes Solr to return an HTTP 500 error response:
> {noformat}
> http://localhost:8983/solr/films/select?fl=[child%20parentFilter=ge]&q=*:*
> {noformat}
> The error response seems to be caused by the following uncaught exception:
> {noformat}
> java.lang.NullPointerException
> at
> org.apache.solr.response.transform.ChildDocTransformer.transform(ChildDocTransformer.java:92)
> at org.apache.solr.response.DocsStreamer.next(DocsStreamer.java:103)

> {noformat}
> In ChildDocTransformer.transform, we have the following lines:
> {noformat}
> final BitSet segParentsBitSet = parentsFilter.getBitSet(leafReaderContext);
> final int segPrevRootId = segRootId==0? -1:
> segParentsBitSet.prevSetBit(segRootId - 1); // can return -1 and that's okay
> {noformat}
> But getBitSet can return null if the set of DocIds is empty:
> {noformat}
> return docIdSet == DocIdSet.EMPTY ? null : ((BitDocIdSet) docIdSet).bits();
> {noformat}
