Description

SolrJ depends on HttpClient 4.2.x right now, but HttpClient 4.2.x has issues that the ManifoldCF team encountered with handling of form data encoding - issues which are addressed in HttpClient 4.3.x. We developed a local patch, but Solr will eventually need to go to the new client. (ManifoldCF would plan to follow shortly thereafter).

I tried to get Oleg (PMC chair of HttpComponents) to agree to port the fixed code to the 4.2.x stream but he did not want to do that. So I believe that that avenue is closed.

See CONNECTORS-623 for a detailed description of the problem.
