The embarassing existence of unconditional jumps (read goto's) in Java. It (goto) is like a zombie that refuses to just die.

Goto.java

public class Goto {

        public static void main(String[] args) {
                int count = 0;
                Goto:
                for(int i = 0; i < 10; i +=1) {
                        for(int j = 0; j < 10; j += 1) {
                                System.out.println("hello" + count++);
                                break Goto;
                        }
                }
        }
