the dfltcc hardware compression has no guarantee to generate the exactly
same output for the same input. the zlib and deflate RFC 1950 and 1951
also don't guarantee that multiple runs with the same input data will
generate the same output.

if reproducible deflate is needed by openjdk the calls need to set
DFLTCC=0 before calling zlibs-deflate.
