A new check for VK_RMENU is generating new modifier bits for the right ALT key causing shortcuts to fail.
http://hg.openjdk.java.net/jdk/jdk/file/ba545e52b932/src/java.desktop/windows/native/libawt/windows/awt_Component.cpp#l2718 See bug # 8194873 https://bugs.java.com/bugdatabase/view_bug.do?bug_id=JDK-8194873 For example: JOptionPane.showConfirmDialog(this, "Do you wish to save file?", "Confirm", JOptionPane.YES_NO_CANCEL_OPTION) When you type left ALT+Y it works, but right ALT+Y does NOT work. This is a regression added in Java9. Please fix asap, thanks. -- Peter Quiring
