Emmanuel Lecharny commented on DIRMINA-1044:
--------------------------------------------
Yes, we are most certainly going to release a 2.0.15 quite soon. I still have
to double check that it works fine with SSHD and ApacheDS.
In any case, if I start a vote tomorrow, it will take 3 days to ht the world,
so expect a release by next monday, at best.
Many thanks for having double checked teh fix :-)

> We have already debugged a bit in the Mina SSL Filter and identified the
> following:
> - During step 2, we see a SSLHandshakeException that will be thrown in the
> {{org.apache.mina.filter.ssl.SslFilter.messageReceived(NextFilter, IoSession,
> Object)}} method. But the SSL Filter seems to not handle such kind of
> Exception ({{org.apache.mina.filter.ssl.SslFilter.exceptionCaught(NextFilter,
> IoSession, Throwable)}} only handle WriteToClosedSessionException)?
> - From the javadoc
> [https://mina.apache.org/mina-project/apidocs/org/apache/mina/core/service/IoHandler.html#exceptionCaught(org.apache.mina.core.session.IoSession,%20java.lang.Throwable)]
> it seems to be that Mina itself handle IoExceptions and close the
> connection. SSLHandshakeException is a IoException, but as described above,
> the connection is *NOT* closed. Additional Remark: The javadoc is for the
> IoHandler, not for IoFilter - so I am not sure if this rule also applies to
> the IoFilter?
> We have not yet an proposal how to fix Mina and/or the Mina SSLFilter. We
> will try to workaround with a custom filter which close the session if
> SSLHandshakeException failed.
> We have testet the problem with Mina 2.0.13 and 2.0.14.
