The new methods makeXXXSpliterator proposed as part of SplittableRandom does not state the boundary conditions like
===============
index - the (inclusive) lower bound on traversal positions
fence - the (exclusive) upper bound on traversal positions
origin - the (inclusive) lower bound on the (pseudo)random values to be generated
bound - the (exclusive) upper bound on the (pseudo)random values to be generated
=============
It needs to be enhanced to state any exception scenarios based in input parameter boundary checks.
