netty

Hello Experts,

could someone please explain to me, how in netty "Downstream Exceptions" are handeled? According to the javadoc there are no Downstream exceptions:

http://docs.jboss.org/netty/3.1/api/org/jboss/netty/channel/ExceptionEvent.html

Given the case that in one of my downstream handlers an exception occures OR in the I/0 Thread itself, where can these errors be catched and handeled?

thank you very much tom
