getObjectByUuid throws exception instead of returning null as described in javadoc

javadoc of 

ObjectContentManager
public Object getObjectByUuid(String uuid)

sais that the method will return the object found or null. 
So I expected null as return value when no object with the provided id can be found.
This behavior fits the behavior of other methods, such as getObject(String path).

Instead I receive a ObjectContentManagerException with a wrapped ItemNotFoundException. 
By looking at the implementation in ObjectContentManagerImpl 

 public Object getObjectByUuid(String uuid) {

        try {
            Node node = session.getNodeByUUID(uuid);
            Object object = objectConverter.getObject(session, node.getPath());
            requestObjectCache.clear();
            return object;

        } catch (RepositoryException e) {
            throw new org.apache.jackrabbit.ocm.exception.RepositoryException("Impossible to get the object with uuid : " + uuid, e);
        }

    }

it becomes clear that the ItemNotFoundException is not caught individually. Btw: javadoc on this methods is in sync with the code.

I suggest either returning null or making the javadoc more precise on method ObjectContentManager  getObjectByUuid(String uuid)

best regards
Sebastian
