> I've observed that chooseTargets in ReplicationWork may pass incomplete srcPath (not starting with '/') to block placement policy.
> It is possible that srcPath is extensively used in custom placement policy. In this case, the incomplete srcPath may further cause AssertionError if try to get INode with it inside placement policy.
