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.
Compiling the server
git clone https://github.com/apache/lucene-solr cd lucene-solr git checkout ea2c8ba ant compile cd solr ant server
Building the collection
We followed Exercise 2 from the Solr Tutorial. The attached file (home.zip) gives the contents of folder /tmp/home that you will obtain by following the steps below:
mkdir -p /tmp/home echo '<?xml version="1.0" encoding="UTF-8" ?><solr></solr>' > /tmp/home/solr.xml
In one terminal start a Solr instance in foreground:
./bin/solr start -f -p 8983 -s /tmp/home
In another terminal, create a collection of movies, with no shards and no replication, and initialize it:
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.jsonSteps to reproduce Use a Linux machine.

Description
Requesting the following URL causes Solr to return an HTTP 500 error response:
http://localhost:8983/solr/films/select?q=initial_release_date:[*%20TO%20NOW-18YEAR]&wt=php&json.facet.facet.field=2
The error response seems to be caused by the following uncaught exception:
ERROR (qtp689401025-19) [ x:films] o.a.s.h.RequestHandlerBase java.lang.NullPointerException at java.util.concurrent.ConcurrentHashMap.get(ConcurrentHashMap.java:936) at org.apache.solr.schema.IndexSchema.getFieldOrNull(IndexSchema.java:1201) at org.apache.solr.schema.IndexSchema.getField(IndexSchema.java:1225) at org.apache.solr.search.facet.FacetField.createFacetProcessor(FacetField.java:118) at org.apache.solr.search.facet.FacetRequest.process(FacetRequest.java:397) at org.apache.solr.search.facet.FacetProcessor.processSubs(FacetProcessor.java:472) at org.apache.solr.search.facet.FacetProcessor.fillBucket(FacetProcessor.java:429) at org.apache.solr.search.facet.FacetQueryProcessor.process(FacetQuery.java:64) at org.apache.solr.search.facet.FacetRequest.process(FacetRequest.java:401) at org.apache.solr.search.facet.FacetModule.process(FacetModule.java:139) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:298) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:199) at org.apache.solr.core.SolrCore.execute(SolrCore.java:2559) at org.apache.solr.servlet.HttpSolrCall.execute(HttpSolrCall.java:711) at org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:516) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:394) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:340) [...]
There is called method 'get' on the member 'org.apache.solr.schema.IndexSchema.dynamicFieldCache' (which os a 'ConcurrentHashMap') with null as an argument; that leads to a crash inside 'get' method. The null value (passed to 'get' method) comes from from member 'field' of 'org.apache.solr.search.facet.FacetField' instance' at org/apache/solr/search/facet/FacetField.java[118].
