Przemo Pakulski commented on JCR-1803:
--------------------------------------
I've examined that all the libraries are ok.
Problem seems to be related to old issue JCR-487, our version storage still
contains frozen nodes with jcr:frozenUuid field stored as REFERENCE instead of
STRING.
Method internalValue().toString() works in both cases, whilst getString() on
jcr:frozenUUID fails for such nodes :(.
> Node.restore() throws java.lang.ClassCastException
