Unable to catch SocketException in Thread

Question

I have a peculiar problem with my client-server application. The scenario is quite simple:
1. A ServerSocket object accepts a new connection from the client
2. The accepted socket then opens an input and output stream and waits for request from the client (it gets stalled in a read() method).
3. The client sends two requests. In my test setup the execution simply ends here, meaning that the client thread comes to a natural end, causing the client socket to stop existing (I guess ?!?)
Everything seems to progress smoothly with the requests - no errors or exceptions occur along the way, apart from a "SocketException: socket reset" which gets thrown by the accepted server socket's inputstream, since it was stalled in the read() method, after having completed the two mentioned requests. So far so good - it all makes sense, but what I don't understand is why I'm unable to catch that SocketException. My StackTrace leads me to a specific place in my code (I use netBeans to find it) where I actually catch all possible Exceptions, but try to ignore them. However, the stacktrace gets printed anyway, while the message that I wish to print doesn't. The code looks like this:
        while(!isClosed()) {
            final Socket s = accept();           
            Thread t = new Thread(new Runnable() {
                public void run() {
                    try {
                        handleConnectionRequest(s);
                    } catch (SocketException ex) { // THE EXCEPTION SHOULD GET CAUGHT HERE!!!
                        System.out.println("Socket exception");
                    } catch (SocketTimeoutException ex) {
                        System.out.println("SocketTimeoutException");
                    } catch (IOException ex) {
                        System.out.println("IOException");
                    } catch (Exception ex) {
                        System.out.println("Exception");
            t.start();
        }My StackTrace looks as follows:
java.net.SocketException: Connection reset

Sorry guys. When I put my head on the pillow last evening I thought more clearly and came to think that it might be a result of a try catch block longer up the stack handling the IOException. Today I finally found it and by removing it everything works as intended. I simply didn't realise that the printed stacktrace itself wouldn't reveal where the exception was caught and it's stacktrace printed, so I went looking in the wrong place.
