Rob Eden commented on DIRMINA-785:
----------------------------------

Cool, but annoying that this change happened in a maintenance release as it broke all my IoHandlers. Changing the version to 2.1 would have been nice.

> Current MINA implementation doesn't support half-duplex close as described in RFC-793 section 3.5. "Closing a Connection". 
> After the read in AbstractPollingIoProcessor#read() fails due to closed of the input stream whole NioSocketSession#channel is scheduled to close. In such situation only the input part should be closed with call to SocketChannel#socket().shutdownInput(). The whole channel should be closed only after the IoSession#close() call.
