We are working in this area; we are looking to replace the
ConnectionFactory with another mechanism (ConnectionBuilder) which
have this problem.  The ConnectionFactory will still exist, however, 
(though deprecated) and
this problem will be fixed therein.  I have raised Bug 24597 to track

(You should see it in the next release).

Thank you for spotting this.
