JDK7 the use of local variables in anonymous inner classes is not required in addition to FINAL,JDK8, but the JDK will default to final

While reading today, I saw a local inner class, which says that local internal classes can access local variables, but must be final. Because a local variable disappears after a method call, the local variable is stored in the heap with the final declaration, with the same declaration period as the inner class. But I wrote a local inner class that could access a non-final local variable, what's the matter? PS: My JDK is 8 does it have anything to do with this?

public class Jubuneibulei {
public void P (int a, int b) {

Class te{
void print () {
System.out.println (a);
}
}
New Te (). print ();
}
public static void Main (string[] args) {
New Jubuneibulei (). P (111, 222);

}
}
