ConcurrentUpdateSolrServer ignores HttpClient parameter

Since 4.6.1 ConcurrentUpdateSolrServer ignores HttpClient parameter

Here is the source code:

public ConcurrentUpdateSolrServer(String solrServerUrl, HttpClient client, int queueSize, int threadCount) {
this(solrServerUrl, null, queueSize, threadCount, Executors.newCachedThreadPool(new SolrjNamedThreadFactory("concurrentUpdateScheduler")));
shutdownExecutor = true;
}

It calls this with null as 2nd parameter

Thanks
