If I use on client side a JRE which causes the problem I see in the JBoss log file
"JBAS011806: Channel end notification received"
JBoss log

For "JBAS011806: Channel end notification received" I found this:
https://issues.jboss.org/browse/AS7-1338
But if I use on client side the newest JRE 1.7.0_06, JBoss prompts no "Channel end notification received".
Everything is working fine.
It seems its bug inside the JRE, in the NIO part as you mentioned.
In the fixed bug list of JRE 1.7.0_06 are some bugs for NIO listed.

Conclusion:
I will use now on client side at least JRE 1.7.0_06 and I am happy.
