>             Project: Isis
>          Issue Type: Bug
>          Components: Core

>             Fix For: core-1.3.0

> For example: if you have a field that uses an interface (eg Address) and it returns a concrete type (eg EmailAddress) but that type is not explicitly referred to elsewhere (as a return type or parameter) then the SpecificationLoader will never see it. Hence, if that class gets used (eg an EmailAddress is retrieved from persistent memory)  then an exception will occur.
> The best long term solution is to load all classes from the Jar(s) that contain the DOM code.  This could be indicated by placing a marker, such as a file, in the metadata.of the Jar.
> In the meantime a simple workaround is to add a method, typically to a service, that uses the concrete class and mark it as hidden. Give the method a name that makes it clear what the method is there for so nobody tries to use it.
