Carusyte can you provide us with the code that makes this happen?

>             Project: MINA
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 2.0.2
>         Environment: XP, JDK 1.6
>            Reporter: Carusyte
>            Priority: Critical
>              Labels: deadlock
>             Fix For: 2.0.14
> I am using a NioSocketConnector inside a NioSocketAcceptor (like a message broker / proxy
app), and I need to use the connector in synchronous mode therefore I have to call IoFuture.await()
or the method alike.
> The problem is, as I look into the source code, when it comes to ConnectionFuture.await(),
if the connection is not ready, DefaultIoFuture.checkDeadLock() will be called, iterating
through the stack trace of current thread, checking to see if AbstractPollingIoProcessor is
involved in the trace, and if so, throw a dead lock exception. The point is, IMHO, this AbstractPollingIoProcessor
is created by the NioSocketAcceptor, not by the NioSocketConnector, and thus shouldn't be
interpreted as a dead lock threat.
> How can I work around this issue?
