OCM will make all Objects annotated with @Node into nt:unstructured node types unless you specify a value for the jcrType property. The default value for discriminator should be true so I would have thought that it could map back to your JCRContent object.
Personally I have found it much easier to work with XML configuration files for OCM instead of annotations. You will probably find it easier to handle all your mapping in one file and it saves recompiles for small changes that you may have for deployed applications.
