I compared for JDK9 the two tarballs (old and new hash) and there is no
difference in the content (according to diffoscope). Also, if I
hg-clone the repository/tag (and add the .hg_archival.txt file), all
three directory trees have the same hash value according to guix hash
-rx

Thus, it seams like their artifacts are not stable, as we saw it
for autogenerated artifacts on github.

I will check the same for JDK10 and will prepare a patch within the
next two days.
