Marcel Reutegger updated OAK-6410:
----------------------------------
Affects Version/s: (was: 1.4)
(was: 1.2)
(was: 1.0)
Labels: (was: candidate_oak_1_0 candidate_oak_1_2
candidate_oak_1_4)
Versions 1.4 and older are not affected. With those versions the implementation
throws a VersionException because the node is checked in. In my view this is
legitimate as well. The JavaDoc says: "throws VersionException - if this node
is read-only due to a checked-in node and this implementation performs this
validation immediately."
> NPE when removing inexistent property from checked in node

> session.save();
> session.getWorkspace().getVersionManager().checkin(child.getPath());
> Node node = (Node) session.getItem("/parent/child");
> node.setProperty("inexistent", (Value) null);
> {code}
