When using Solrj client and setting query params:
queryParams.setMissing("true")
or
queryParams.set(FacetParams.FACET_MISSING, "true")
I'm getting an exception as below:
...

I guess that's because when "facet.missing" parameter is set to true Solr is
returning response containing "int" element with no name that causes the
problem. Response may look like:
<lst name="genre">
<int name="rock">5559</int>
<int name="soul">5547</int>
<int name="punk">5412</int>
<int>0</int>
</lst>
Do you know if this bug is already logged?
Cheers
Tomasz
