[kaffe] [BUG] jar creating duplicate entries

[Daniel Bonniot]

Hi,

When using kaffe's jar tool in update mode, I noticed the jar file ends up 
with duplicate entries. Then if you update again, thre entries for the same 
file, ...
This makes the jar grow indefinitely, and be invalid.

I put up a testcase at:

Run run make, and see how bad.jar has twice as many entries as good.jar. If 
you run make again, it keeps growing.
