George Gastaldi commented on FORGE-1199:
----------------------------------------

It does not work in Forge 2 either:

Here is a test case reproducing that:

> I need to unmarshal some XML using JAXB.

>                 </exclusion>
>             </exclusions>
>         </dependency>

>         final JAXBContext context = JAXBContext.newInstance(Model.class);
