The fix to 7042566(?) results in two methods such as
  void foo(int... ia) {}
  void foo(Object... oa {}
as now seen as both matching when foo is given two ints.
Test code:

public class test4 {
    public int foo(int ... vai)   { return 1; }
    public int foo(Object ... vaO) { return 2; }

    //TEST: choose best of overloaded methods
    public int test()    {
        int i1 = 1;
        int i2 = 2;
        int ret = foo(i1,i2);  //should choose method 1
        return ret;
    }

    public static void main(String[] args)    {
      test4 tv = new test4();
      System.out.println( tv.test()==1?"PASS":"FAIL" );
    }
}

Error message:
h:\ws\7_int\tools\src\javac\varargs\test4]javac test4.java
test4.java:18: error: reference to foo is ambiguous, both method foo(int...) in test4 and method foo(Object...) in test4 match
