Something like this:

  |    public <T> void registerMapper(Class<T> clazz, MetaMapper<T> metaMapper)
  |    {
  |       ClassInfo ci = configuration.getClassInfo(clazz);
  |       ci.setAttachment(MetaMapper.class.getName(), metaMapper);
  |    }
  | 
  |    MetaMapper<ObjectName> onMetaMapper = new ObjectNameMetaMapper();
  |    registerMapper(ObjectName.class, onMetaMapper);   
  | 
You only need to be careful for transient ClassInfos,
since it's all weak (value) hash map in the background.

But for jdk classes this should stick in there forever. :-)
