Because it is actually a bug in Java, not in OpenSSL. It is just that
recent OpenSSL versions enable a feature (Session Tickets) that is
standards-wise backwards compatible.  Arguably, distributions could
choose to not enable the feature by default, but that doesn't have my

This change adds a option to choose if the feature is used, and disables
it by default because there is no further support in our SSL code for
it and it immediately helps fix a problem that I don't think will be
resolved server-side any time soon.
