Emacs can have built-in GnuTLS library and make a STARTTLS connection
without external programs such as gnutls-cli.  Wanderlust uses this
feature when available.  You can confirm whether your emacs has
built-in GnuTLS library by evaluating (gnutls-available-p) .  If your
emacs uses gnutls-cli despite of having built-in GnuTLS library, you
may modify elmo-network-stream-type-alist variable.

The problem was that starttls-negotiate-gnutls function couldn't
detect the end of the handshake.  It is indicated by starttls-success
variable.  The varialbe's default value is "- Compression: ", but
which does not be outputted by gnutls-cli 3.6 anymore.  So you need to
change starttls-success's value accroding to actual gnutls-cli's
output.  starttls-negotiate-gnutls removes the TLS negotiation junk
before finish.
