I think using the system zlib (or libz as it seems to shipped as on
Solaris and MacOSX) would have been okay with jdk6, it's just that the
zip64 support in jdk7 changed total_in/out to "long long".
The copy that we have in the jdk repository at this time is 1.2.5. I'm
not aware of any updates that avoid this patch but I think the right
thing is to change the java.util.zip code so that it works with an
unmodified zlib. I think Sherman has ideas on this, just hasn't got to
it yet. If you have cycles to look at it that would be great (and I
understand that distributions would frown on attempts to bundle a
private copy with OpenJDK).
