>                 Key: SOLR-13187
>                 URL: https://issues.apache.org/jira/browse/SOLR-13187
>             Project: Solr
>          Issue Type: Bug
>    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:

> The call to {{getQueryPlugin}} from {{org.apache.solr.search.QParser.getParser()}}, at
line 366, can return a null pointer, as witnessed by the URL above. Method {{getParser}} should
probably check for this.
