subject Phony overloading of static fields coming from Java classes
code 
// File Statics.java
package test;

class Superclass {
    public static final int x = 42;
}

class Subclass extends Superclass {
    public static final double x = 42.0;
}

class JavaMain {
    public static void main(String[] args) {
        System.out.println(Subclass.x);
    }
}

// File Main.scala
package test;

object Main {
  def main(args: Array[String]): Unit = {
    System.out.println(Subclass.x);
  }
}
what happened 
scalac complains with the following error:

Main.scala:5: ambiguous reference to overloaded definition,
both value x: scala.Double(42.0)
and  value x: scala.Int(42)
match expected type <any type>
    System.out.println(Subclass.x);
                               ^
one error found
what expected No error, as there is really no overloading here, at least from Java's point of view (class JavaMain works as expected). This doesn't seem to be a huge problem, as it is possible to work around it by giving an explicit type, but I think that either the specification or the implementation should be changed.
