Issue with HttpClient in RTC 4.0.2

I am seeing what I believe is a know bug with the Apache HttpClient, version 1.4.2, which I have confirmed is the version in my RTC4.0.2 installation. Here is a link to the issue: https://issues.apache.org/jira/browse/HTTPCLIENT-1118

It's not clear from that link which release this is fixed in. Is it possible to determine that, and upgrade the version packaged with RTC 4? Is there a way I could deploy version 1.4.1 as a workaround? Please advise how I would do this.

For reference, here is the exception I am getting in my installation:
java.net.UnknownHostException: usfdeveloper

It produces this error message:
javax.net.ssl.SSLException: hostname in certificate didn't match: <usfdeveloper/9.24.239.218> != <usfdeveloper>

Thanks
