Bug 50502 Change signature refactoring doesn't update JavaDoc comments
I have a class with abstract method. I use the change signature to change the signature of the method. If I delete field, I would expect it to delete the @param from the comment. If I add field, I would expect it to add @param with TODO to the comment. Also all the derived classes have javadoc with @see original method signature. When the refactor changes the signature of all the derived/implementing classes, it should update the @see with new method signature.

package p;
abstract class A {
	public abstract int m(String[] bbb[][], int abb);
}
class B extends A {
	public int m(String[] bbb[][], int number) {
		return number + 0;
	}
}
class C extends B {
	public int m(String[] strings[][], int abb) {
		return abb + 17;
	}
}
