----------------------------
> Classes that are not referenced in the DOM aren't found by the specification
> loader
> -----------------------------------------------------------------------------------
>
> Key: ISIS-236
> URL: https://issues.apache.org/jira/browse/ISIS-236
> Project: Isis
> Issue Type: Bug
> Components: Core
> Affects Versions: core-1.0.0
> Reporter: Robert Matthews
> 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.
