      Description

        The number of opened files used in select() on MacOSX is limited to 1024 (FD_SETSIZE).
        The following sequence can illustrate the problem:
        1. Open 1023 files (use FileInputStream())
        2. Create socket and try to read from it.
        3. Get the following exception:
        Exception in thread "main" java.net.SocketException: Invalid argument
        at java.net.SocketInputStream.socketRead0(Native Method)
