HubNet SocketTimeoutException

[ptgrogan]

I received a java.net.SocketTimeoutException while running a HubNet activity in my class last night. We had about 20 students connected to a HubNet server running the default Disease HubNet model. The error was generated as the activity was wrapping up (the model had been running for a several hours previously) and I believe at least one student was issuing rapid commands at the time.

The error message does not provide much information; however, I suspect it may be an issue with network connectivity rather than a true bug. Posting the error message for completeness.

Thanks for reporting!

We recently received another report of this. It was (like this and #1478) an error that occurred on Windows. I haven't had time to put together a failing test case, but it smells like a Java Bug to me that the socket is even throwing this exception, given that setSoTimeout(0) has been called on it. I think the argument for this is bolstered by the fact that it has only occurred on a single operating system (and rarely at that). I couldn't find anything in the Java Bug tracker, but before investing too much time fixing this, it's probably worth checking again whether a similar bug has been reported.
