Sockets: setSoTimeout() not working with Scanner

Question

I'm implementing the timeout feature for a server, and I've run into a problem. My server reads from the socket input stream using a Scanner, and I've set the socket timeout using Socket's setSoTimeout() method. This is supposed to throw a SocketTimeoutException, but instead, the Scanner is throwing a NoSuchElementException first (because it's not getting the right input!) and the SocketTimeoutException never gets thrown. If I use InputStream's read(), I don't have this problem (SocketTimeoutException gets thrown properly). Here's how my code is organized:
Accept connection.
Set so timeout.
Spawn thread with socket as its argument.
- Try:
- Decode request from the socket's input stream.
- Catch SocketTimeoutException:
- Send timeout message to client.
Close connection.
Do you know a way around this issue besides replacing Scanner with read()? Or did I do something wrong?
