Thx for the test-build. I will give it a try as soon as possible.

>             Project: MINA
>          Issue Type: Bug
>          Components: SSL

>            Priority: Critical
> I’m facing a critical problem in my project with an MINA-stack including SSL. My Protocol-IoFilterAdapter
receives corrupt messages under heavy load (JMeter-Benchmark with 300 Threads and round about
5-10 MINA-calls per thread). The Problem disappeared without SSL, so I debugged for some days,
and I think the problem occurred because of the changes made for fixing the issue [DIRMINA-1019|https://issues.apache.org/jira/browse/DIRMINA-1019]
([commit|http://git-wip-us.apache.org/repos/asf/mina/commit/9b5c07f9]). I think the problem
is that the SSLHandler is calling messageReceived while also writing data into the next filter,
which is writing inside the messageReceivedEventQueue. With the fix provided inside the race-condition-ticket,
it works like a charm. So I think that the answer of the question "Why the second loop is
also protected by the loop?" is: because otherwise the messageReceivedEventQueue gets corrupted
