---------------------------------------------

Tested from the trunk. Still failing when trying to communicate with Cloudwatch. Stacktrace:

>             Project: HttpComponents HttpClient
>          Issue Type: Bug
>          Components: HttpClient
>    Affects Versions: 4.3 Alpha1

> As noted on the AWS developer forum here: https://forums.aws.amazon.com/message.jspa?messageID=417487,
an IllegalStateException occurs when attempting to connect to AWS while using 4.3-alpha1
> I stepped through the code, and found that the failure occurs at line 132 in the open(...)
function in org.apache.http.impl.conn.AbstractPoolEntry.
>     Asserts.notNull(this.tracker, "Route tracker");   <== FAILS | this.tracker is
null
> Commenting lines 132 and 133 made the problem go away (ie, I was able to communicate
succesfully with AWS, with no errors or warnings), though I've done no research into what
a proper fix might be.
