title: What version of httpclient is compatible with the Amazon SDK v 1.11.5?
body: <p>I’m using the Amazon Java SDK, version 1.11.5 (I included the aws-java-sdk-1.11.5.jar in my WEB-INF/lib directory).  What version of the Apache httpclient library do I need to include that is compatible with this version of the AWS SDK?  I tried httpclient-4.3.4.jar, but I get the below error</p>
