Comment (by abrax5):

 I'm not really that familiar with Java, but looking at this:

 The protected constructor for an SSLContext allows you to specify an
 SSLContextSpi. Maybe we could override SSLContext implementation with one
 that uses an SSLContextSpi derived from the default one, that just differs
 in what it would return for {{{engineGetClientSessionContext()}}}. This
 method returns an SSLSessionContext which allows enumerating SessionIDs.

 These are just some rough ideas, but may through this path we could tell
 the TLS engine to try reusing a session. We don't really need access to
 the masterSecret of the session, I think. We just need to make sure that
 the TLS engine can find the old ID and advertise the reuse ID to the
 server in the CLIENT_HELLO msg.
