Java is known to be broken with respect to the last ten years or so of 
changes to the tzdb data format.  You'll need to generate "rearguard" 
format data to feed to the Java updater.

Paul also helpfully provides rearguard tarballs on his webpage 

You can easily generate those yourself by running make 
rearguard_tarballs on the distribution from iana.org.

It seems silly to pull one release from an archive going back to 1993 
because one third-party implementation (even if it's a popular one) 
cannot cope with the data format.
