jar command shows "bit length overflow"

[Weijun Wang]

I just rebuild jdk8/tl on Windows and calling "jar uvf" shows a lot of

   bit length overflow
   code ?? bits ?->?

A little grep shows 
jdk/src/share/native/java/util/zip/zlib-1.2.5/trees.c could print this. 
Something goes wrong or is it just me?

Said that, it looks like the jar file is fine.

Thanks
