Do you mean like this:

-            ByteBuffer src = ByteBuffer.wrap("hello".getBytes("UTF-8"));
+            String str = "hello integer" + new Random().nextInt(10000);
+            ByteBuffer src = ByteBuffer.wrap(str.getBytes("UTF-8"));

And I don't known how to discard meaasge doesn't match what we expect.
