Hi,
what I can see from the 2 blocked threads is that one his holding a lock
on the SM context, then tries to write something over a TLS connection,
while the other receives something through the TLS connection, and tries
to process a SM event.
There is a clear inter-blockage, with thread 1 doing:
- hold lock on the SSLHandlerG0 instance in the finish_handshake
function (which is synchronized)
- get a lock on the SM context
and thread 2 doing:
- hold a lock on the SM contect
- and tries to get a lock on the SSLHandlerG0 instance to write
something that is generated in the verifyAndSendStartMsgs function.
The finish_handshake method will prob-pagate the Session_secured event
to the IoHandler, and I think it's a good idea to handle it before
trying to write anything. That means you need to avoid writing anything
until the session_secured event has been handled.
I wonder if the verifyAndSendStartMsgs should not be sent in
session-secured event rather than in the session-opened...

We cannot share the source code,i have tried with latest Mina
version 2.2.3 also,this is also not working.Dead lock is
happening.Our Organization won't allow to share the source
code.I am sure there is an issue with the state machine and
Apache mina SSL used together.Please let me know how to proceed
on this further ? i am open to zoom or webex call .
