As this an interface method with default implementation, I think, it should be
clear whether this states a method contract for all implementors or an
implementation detail of
the default implementation. Here it's not in the @implNote section, so
I assume that the new statement
tightens the specification for all possible implementors (probably
making valid Java-8 code invalid in Java-9
if somebody reimplemented chars() for custom CharSequence in
non-late-binding manner).
Is this spec change intended?
With best regards,
Tagir Valeev.
