Messages Logged as being sent but never sent over the wire

We had an issue with QuickfixJ where the logs told us that messages were being sent, but were infact never sent over the wire. A network trace and the resulting actions from the counterpart that we were connected to also proved that messages were never sent. What seemed to happen is that after a certain point, no messages were sent to the other party.

the strange things is that this issue only ocured on one of our platforms and we could not reproduce it on any other platform.

After diggind in QuickfixJ code and Mina code, i made several changes: those described in QFJ-296 and some others in the IoSessionResponder.java class. this seemed to resolve this issue. i wanted to get your feedback on these changes and see what you think.
