[Bug libgcj/13102] New: java.net.Socket#connect doesn't work after java.net.Socket#setSoTimeout

["artem at bizlink dot ru" <gcc-bugzilla at gcc dot gnu dot org>]

When using java.net.Socket interface introduced in Sun JDK1.4,
which allows for connection timeouts, connection attempt throws:
'Exception in thread "main" java.net.SocketException: Socket closed'.

(Version 3.4 20030830 has the same bug too).

Testcase (throws Exception becouse of the bug):

/**
 * New socket interface is important for its connection timeouts.
 */
public class TestSocket {
  protected static void test( boolean set ) throws Exception {
    java.net.SocketAddress sa = new java.net.InetSocketAddress( "gcc.gnu.org", 
80 );
    java.net.Socket socket = new java.net.Socket();
    if( set ){
      // Any of these options leads to "Socket closed" exception.
      socket.setTcpNoDelay( true );
      socket.setSoLinger( false, 1 );
      socket.setSoTimeout( 20 * 1000 );
      socket.setKeepAlive( false );
    }
    socket.connect( sa, 30 * 1000 ); // Timeout is 30 seconds.
    socket.close();
  } 
  public static void main( String[] args ) throws Exception {
    test( false ); System.out.println( "Socket works without options." );
    test( true ); System.out.println( "Socket works with options!" );
  }
}
