I came accross with the same problem: - ubuntu, java 1.5.0_22, ant 1.8.2 - suse, java 1.5.0_08, ant 1.9.0 (yes not the identical environments but.. in 1.8.x it was working..)
Manifest is genereated in jar taks. there were following differences: - Manifest: only content of Ant-Version: , and Created-By: (that could not make problem) - differences of jar files length, jar from 1.8 has 6.2kB, jar from 1.9 has 6.3kB, --> i thing this shows to different compressing. and if I compare displayed content with kdiff3, it is different in some parts. As I have read in discussion thred something changed in zip algorithm. Question is, if there is a way to create "old style" compressed jar.
