I debugged a little bit, because we have the same exception log on session timeouts of users. The reason, why there is an IOException thrown is: there is no value defined for parameter “org.atmosphere.cpr.Broadcaster.writeTimeout” (but the atmosphere classdoc mentioned that there is a default of 5 minutes, but i could not find any place where that default is really set) - and this way it does not follow the route to setup a timeout thread and ignore the result, if the current thread gets interrupted by that. But on any other exception it logs that.
Think, Vaadin should add at least such a default to it’s internal atmosphere setup/init to get rid of IOException logging and let that (correctly?) handled by a timeout.
