Perhaps I'm not making myself clear enough. We can cope with *this*
change either by using rearguard or changing the parser. However, the
tzdb author is determined to push ahead with whatever data changes he
sees fit (calls for more tzdb backwards compatibility are rejected).
At some point, he will add an out of bounds change here that can't be
represented in rearguard or in Java. We need to make a change here to
protect ourselves from that, and to fix what is in many ways a bug in
the Java API - caused by a misunderstanding of their file format.
