School's out, and there's the childish behavior. Someone with nickname "Java Cpp Development" posted comments on a video featuring me at an event saying that no one likes me. On another video, that person posted a comment claiming that OpenPDF is better thab iText, ignoring the fact that OpenPDF is nothing more than an iText version dating from 2009 to which some minor changes were applied.

Ah well, haters gonna hate, hate, hate, hate, hate, but I'm gone shake it off, shake it off.

Childish behavior on YouTube

You must feel really insecure and inferior if you have to resort to this kind of behavior ;-)
