Description

I'm trying to upgrade to 1.5 using existing 1.3.x repository. Restore of versionable node throws ClassCastException.

Caused by: java.lang.ClassCastException: org.apache.jackrabbit.uuid.UUID
at org.apache.jackrabbit.core.value.InternalValue.getString(InternalValue.java:436)

It seems that bug has been introduced already in 1.4 as part of JCR-926 (InternalValue cleanup).

• frozenUUID = UUID.fromString(node.getPropertyValue(QName.JCR_FROZENUUID).internalValue().toString());
  + frozenUUID = UUID.fromString(node.getPropertyValue(QName.JCR_FROZENUUID).getString());

Probably one of the assumptions made was wrong :

• The type of QName.JCR_FROZENUUID is STRING (Object.toString() was used before).
