Description
Make JDO PersistenceManagerFactory accessible so can be interacted with outside of Isis runtime
Invalidate Isis spec cache by way of class (not just by object).

need to be able to do similar with the DN metadata:

Assuming that there's auto-enhancement within the IDE, this means that JRebel picks up each class twice: once for the unenhanced class, then almost immediately for the enhanced class. Therefore, I think that all that may be required is to remove the ClassMetaData whenever an unenhanced class is reloaded DN's will lazily recreate metadata as required.
An enhancement might be to do the enhancement within the JRebel plugin (and not in the IDE). This would require the enhancement is done in a separate classloader; it (obviously!) isn't allowed to reference the java.lang.Class being loaded within the plugin itself. As enhancement does cause this to occur, it must be namespaced off to a separate classloader.
