After upgrading the current release of pip from the bundled wheel specific to Jython 2.7.0, we get problems like the following:

$ dist/bin/jython -m pip install nose
Collecting nose
/Users/jbaker/jythondev/jython27/dist/Lib/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:84: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
...

I should point out that Jython is in fact *secure*, and uses the CAs bundled as part of the Java release, so this is a false positive. But we can readily fix by supporting SSLContext. There are other advantages, including SSLContext avoids reading CA cert files on every verified SSL connection.
