Abstract Mapping and Interface

Hello,

i'm using JiBX 1.1.5 with abstract Mapping. I have a problem where the type in my mapped object is an interface.

For example i have the folowing mapping :
<mapping
class="mypackage.AttributeVO"
abstract="true" type-name="cfile">
<value name="PATHFILE" field="pathFile" type="java.lang.String"/>
</mapping>

I have a other mapping who reference it:

<mapping
class="mypackage.RootVO"
name="ENVELOPPE">
<structure name="ROOTFILE" field="rootFile" map-as="cfile" usage="optional"/>
</mapping>

The RootVO classe reference an interface IAttributeVO (AttributeVO implements it). The binding could not compile. when i replace the interface by the implementation, the compilation is OK.
