Subject [jira] [Commented] (DIRMINA-885) session is closed before the server writes back to the client
Date Wed, 08 Feb 2012 06:50:59 GMT

    [ https://issues.apache.org/jira/browse/DIRMINA-885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13203317#comment-13203317

Emmanuel Lecharny commented on DIRMINA-885:
-------------------------------------------

If the client has closed the connection, it does not make any sense to try to flush something
in the channel : it won't get sent anyway. This is why we don't inject the messages to the
queue.

work correctly as expected, but MINA closes the session before my encoder is called. As I
looked into the source code, AbstractPollingIoProcessor seems to schedule a session remove
as long as the # of bytes read from the channel == -1 (line 673 and line 706). As per the
documentation of java.nio.channels.ReadableByteChannel.read(ByteBuffer dst), this method returns
-1 if the channel has reached end-of-stream, but is it really necessary to close the session
even before the client receive any response?
