Motivation:
SslHandler currently throws a general SSLException if a wrap attempt
fails due to the SSLEngine being closed. If writes are queued the
failure rational typically requires more investigation to track down the
original failure from a previous event. We may have more informative
rational for the failure and so we should use it.
Modifications:
- SslHandler#wrap to use failure information from the handshake or prior
transport closure if available
Result:
More informative exceptions from SslHandler#wrap if the SSLEngine has
been previously closed.
