[jira] [Updated] (SOLR-13202) Three NullPointerExceptions in
org.apache.solr.search.JoinQuery.hashCode()
[ https://issues.apache.org/jira/browse/SOLR-13202?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Cesar Rodriguez updated SOLR-13202:
-----------------------------------
Description:
Requesting any of the following URLs causes Solr to return an HTTP 500 error response:
{noformat}
http://localhost:8983/solr/films/select?fq={!join%20from=b%20to=a}
http://localhost:8983/solr/films/select?fq={!join%20to=a}
http://localhost:8983/solr/films/select?fq={!join}
{noformat}
The error response seems to be caused by the following uncaught exception:
{noformat}
java.lang.NullPointerException
at org.apache.solr.search.JoinQuery.hashCode(JoinQParserPlugin.java:578)
at org.apache.solr.search.QueryResultKey.<init>(QueryResultKey.java:52)
at org.apache.solr.search.SolrIndexSearcher.getDocListC(SolrIndexSearcher.java:1328)
at org.apache.solr.search.SolrIndexSearcher.search(SolrIndexSearcher.java:567)
at org.apache.solr.handler.component.QueryComponent.doProcessUngroupedSearch(QueryComponent.java:1434)
at org.apache.solr.handler.component.QueryComponent.process(QueryComponent.java:373)
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)
[...]
{noformat}
The problem seems to be related with method {{hasCode}} in the class {{org.apache.solr.search.JoinQuery}}:
{code:java}
@Override
public int hashCode() {
int h = classHash();
h = h * 31 + fromField.hashCode();
h = h * 31 + toField.hashCode();
h = h * 31 + q.hashCode();
h = h * 31 + Objects.hashCode(fromIndex);
h = h * 31 + (int) fromCoreOpenTime;
return h;
}
{code}
The URLs provided above selectively leave uninitialized the fields {{fromField}}, {{fromIndex}}, {{q}}, and {{toField}}, but all of these fields are accessed by this method.
We found this issue and ~70 more like this using [Diffblue Microservices Testing|https://www.diffblue.com/labs/?utm_source=solr-br].

> Key: SOLR-13202
> URL: https://issues.apache.org/jira/browse/SOLR-13202
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> 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
