binding compiler is not aware of inherited interfaces

Consider the following:- (This is similar to Bug JIBX-156)

public interface IFoo
{ }

public interface IBar extends IFoo
{ }

public class Bug_Test implements IBar { }

If I have structure field which is of type IFoo, it fails to realize that Bug_Test is actually implementing it indirectly and throws the error:-
Error: No compatible mapping defined for type IFoo;

However, if I have a seperate mapping for IBar, it realizes that IBar extends to IFoo and eventually realizes that Bug_Test is implementing. It is similar to the above issue with the exception of interface instead of abstract class.

Is there a bug fix available ?
