Inconsistent behavior when encountering overloaded methods

I have the following program

import java.util.*;
import java.util.function.*;

class A<T> {
  void m(T x) { System.out.println("there"); }
  void m(Integer x) { System.out.println("here"); }
}
class Test {
  public static void main(String[] args) {
    A<Integer> x = new A<>();
    Consumer<Integer> y = x::m;
    y.accept(1)
  }
} 

Actual behavior

Depending on the order in which methods "m()" appear in the program, the outcome is different. So, if "m( T x)" is first, the outcome is "there". Otherwise, if "m( Integer x)" is first, the outcome is "here".

Expected behavior

I would expect that the reference "x::m" is ambiguous, so the program should have been rejected.
