Hi @anshupal, good finding! It's an error caused by some improvements in the JDK. You can find how to fix it and the background in one of the book's online extra chapters: https://thepracticaldeveloper.com/book-update-2.5.5/#no-more-spying-on-randoms

If you're liking the book, please rate it on Amazon and/or Goodreads, thanks!
