>             Project: Geode
>          Issue Type: Bug
>            Reporter: Konstantin Ignatyev

> Function interface is defined as 
> public interface Function extends Identifiable { 
>    public String getId();
> ...}
> but that is not correct because Identifiable requires type parameter 
> public interface Identifiable<T extends Comparable<T>> extends Serializable
{ 
>    public T getId();
> }
> so when custom function is defined as 
> class SomeFunction extends FunctionAdapter {
>   override def getId:String = "SomeFunction-v1"
> }
> Java compiler tolerates that, but Scala compiler refuses to compile because  because
String is not compatible with 'Nothing' that is expected from getId because Function extends
Identifiable without specifying type.
> Solution:
> define Function as
> public interface Function extends Identifiable<String>
