Re: Java 5 fails to run jar files created with Ant 1.9.0

["Sentinel.czech" <se...@gmail.com>]

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.

Regards
Vaclav

Yes, that's right.

One option is to the compress' antlib's zip task which already has the
zip64Mode attribute that you can set to "never".  Other than that the
only idea I'd have was running Java's own "jar" via <exec> or <apply>.
