METHOD_ABSTRACT_ADDED_IN_IMPLEMENTED_INTERFACE false positive

[rreich]

Adding a new class implementing java.util.function.UnaryOperator produces a METHOD_ABSTRACT_ADDED_IN_IMPLEMENTED_INTERFACE entry marking the change as source incompatible, which it isn't.

Create this class to reproduce:

package com.acme.japicmp;

import java.util.function.UnaryOperator;

public class NewOperator implements UnaryOperator<Object> {
  @Override
  public Object apply(Object o) {
    return null;
  }
}

NEW (*) public class com.acme.japicmp.NewOperator
