For Java 5+, with varargs you could do (not compiled):

public class MyIoUtils {

   public static void closeAll( Closeable ... toClose ) {
     for( Closeable closeMe : toClose )
       try {
         if( closeMe != null ) closeMe.close();
       } catch( IOException ex ) {
         Logger.getLogger( "MyIoUtils" ).log( ex );
       }
   }
}

and get a somewhat cleaned up try catch

  OutPutStream io1 = null;
  BufferedStream bs = null;
  try {
    io1 = new OutputStream( ...
    bs = new BufferedStream( io1, ...
    // do stuff
  }
  finally {
    MyIoUtils.closeAll( bs, io1 );
  }

Mostly I don't care for deep nesting, I think it reads poorly, and I 
think it can also be hard to trace out for a programmer reading the 
source.  Giving the concept of closing a lot of objects a name like 
"closeAll" promotes literate programming, imo.
