seems confused edit script

[xzm2000]

Hi! I am confused by the edit script in these two java files by gumtree-simple. (Because github can only upload .txt, I changed the name from .java to .txt) old.txt new.txt

My command is: gumtree webdiff old.java new.java -m gumtree-simple I didn't use gumtree because the unexpected change for public class KeyedObjects2D

The result is a little confused, why move and delete here?
