Emmanuel Lecharny commented on DIRMINA-771:
-------------------------------------------
This can certainly be improved. The stack trace is generated because for some
reason, we try to get the localAddress, and it's already closed.
However, this is not really a critical error.
> Calling NioSocketSession.toString() causes java.lang.Error

> Key: DIRMINA-771
> URL: https://issues.apache.org/jira/browse/DIRMINA-771
> Project: MINA
> Issue Type: Bug
> Affects Versions: 2.0.0-RC1
> Environment: WinXP JDK 1.6.1_18
> Reporter: Jörg Michelberger
> Priority: Critical
>
> Hi there,
> using MINA 2.0.0 RC1 and have a log statement in my
> IOHandler.exceptionCaught() method plugged on top of a NioSocketSession.
> The log statement calls toString() on the IoSession passed in. In some cases
> I get the appended Exception.
> Thats not good.
