Why don't you modify markspace's example to see for yourself, e. g.

     @Override
     public void close() throws IOException {
         System.out.println( "Trying to close "
            + getClass().getSimpleName()+":"+name );
         throw new IOException("CloseError " + name);
     }

Then read what the Javadocs have to say about suppressed exceptions.
