Chetan Mehrotra commented on OAK-1233:
--------------------------------------
First note that higher the numeric value means latest the revision is as the
values here are based on zero
So following things would have happened
* On C1 document was split at rev r14298e45a64-0-2 (7087856) *BUT* the highest
revision for property async-status is actually 7082166-0-2
* On C2 document split was done at r14298e4548d-0-1 and the highest rev is same
* On Oak side when the previous revision list is sorted in
NodeDocument#getPreviousRanges it puts the rev list corresponding to
r14298e45a64 *before* r14298e4548d. But actual entries within those two list do
not confirm to the rule of _first element of the next iterator is greater
than the first element of the previous iterator_.
So as a fix we probably need to sort the list obtains in
NodeDocument.getPrevisiousDocs
