Johannes Kloos updated SOLR-13180:
----------------------------------
Environment:
Running on Unix, using a git checkout close to master.
h2. Steps to reproduce
* 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 above.
h2. 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}
h2. Building the collection
We followed Exercise 2 from the quick start tutorial
([http://lucene.apache.org/solr/guide/7_5/solr-tutorial.html#exercise-2]) - for
reference, I have attached a copy of the database.
{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:
{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}
was:
Running on Unix, using a recent git checkout of master and the films example
database.
h2. Steps to reproduce
* 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 above.
h2. Compiling the server
{{git clone [https://github.com/apache/lucene-solr]}}
{{cd lucene-solr
git checkout ea2c8ba
ant compile
cd solr
ant server
}}
h2. Building the collection
We followed Exercise 2 from the quick start tutorial
([http://lucene.apache.org/solr/guide/7_5/solr-tutorial.html#exercise-2]). 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:
{{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}}

> Requesting the following URL gives a 500 error due to a ClassCastException in
> o.a.s.s.f.FacetModule: [http://localhost:8983/solr/films/select?json=0]
> The error response is caught by an uncaught ClassCastException, with the
> stacktrace shown here:
> java.lang.ClassCastException: java.lang.Long cannot be cast to java.util.Map
> at org.apache.solr.search.facet.FacetModule.prepare(FacetModule.java:78)
> at
> org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:272)
>
> The cause of this bug is similar to #13178: line 78 in FacetModule reads
> {{jsonFacet = (Map<String, Object>) json.get("facet")}}
> and assumes that the JSON object contained in facet is a JSON object, while
> we only guarantee that it is a JSON value.
> Line 92 semms to contain another situation like this, but I do not have a
> test case handy for this specific case.

> campaign|https://www.diffblue.com/blog/2018/12/19/diffblue-microservice-testing-a-sneak-peek-at-our-early-product-and-results].
