Why not, but the compiler for the old format isn't provided by
openjdk-8, so we'll have another issue when openjdk-7 is removed
(probably in Jessie+1). The old compiler would have to be copied into

Alternatively, we may also try backporting the new format to openjdk-7.
Thus we would only keep the most recent format.

Like #5 I think we lack the time to properly test a porting solution
before the freeze.

If we go with #2, where should the tzdb.dat file be installed? Into
/usr/share/javazi or another directory to avoid mixing the two formats?
For example the Fedora package installs it in /usr/share/javazi-1.8 (but
if the file is reused for OpenJDK 9 I'd rather avoid coding the JRE
version in the path).
