Hoss Man commented on SOLR-6547:
--------------------------------

i suspect this has something to do with the code in 
CloudSolrServer.condenseResponse ?

I honestly have no idea what that method is for or what it's doing, but a quick 
grep suggests that's the only place in the code base where a "long" value is 
getting assocaited with "QTime"

* CloudSolrServer.condenseResponse should be fixed to use an int for QTime
* SolrResponseBase.getQTime can (and probably should) be hardended to do 
something like this instead of just a direct Integer cast...{code}
return ((Number) header.get("QTime")).intValue()
{code}...that kind of pattern can help protect us in the future if we decide 
that QTime *should* be a long

> CloudSolrServer query getqtime Exception
