Broken shaded internal in kafka sender

Bundled version of LazyCloseable in kafka-sender 1.0.2 is broken :

...
   public void close() throws IOException {
      T maybeNull = this.maybeNull();
      if (maybeNull != null) {
         Util.checkArgument(maybeNull instanceof Closeable, "Override close() to close " + maybeNull, new Object[0]);
         ((Closeable)maybeNull).close();
      }
   }
...

In the close method, the Util class is not imported neither shaded in the jar. This leads to a ClassNotFoundException when calling this method.

Oh ok 😃 I see that you removed the usage of Util.

yeah it was an oversight and this problem could bite other libraries, too… Thanks for the shade fix, though!

thanks will fix
