> While trying to serialize and deserialize {{SolrInputDocument}} using the following code, 
> {code:java}
> final SolrInputDocument inputDoc = new SolrInputDocument();
>         inputDoc.addField("foo", "bar");
>         Gson gson = new Gson();
>         String docString = gson.toJson(inputDoc);
>         SolrInputDocument solrInputDocument = new SolrInputDocument(gson.fromJson(docString, SolrInputDocument.class));
> {code}
> the deserializing fails w/ 
> bq. "java.lang.ClassCastException: Cannot cast com.google.gson.internal.LinkedTreeMap to org.apache.solr.common.SolrInputDocument"
> {{SolrInputDocument}} needs an empty constructor for this.
> There seem to be some ways to get around this for older versions but with vanilla code this affects all versions starting 5.5 all the way until 8.11.1
