Hi Jakob,
I guess if you want to call it a "severe" bug, then it's a bug in the
documentation.
I will put a comment in the Javadoc to prevent confusion when mapping
files are used. The problem is that the Mapping handles it's own class
loading, for files which are defined in the mapping, which is why you
can set a class loader for the Mapping object as well. Many people don't
use mapping files, they rely on Castor generated source code or
introspection, so the ClassLoader set with the Unmarshaller will work in
those cases. Also, The unmarshaller will not set the ClassLoader for the
Mapping, it's up to the user to handle that.
The best thing to to do is set the ClassLoader in 3 places:
Marshaller, Unmarshaller, and if a mapping file is being used then the
Mapping.
Thanks,
--Keith
