I believe it's the content specific.  However I couldn't upload our data because
it's confidential.  Your testcase is crucial in this case.
Hopefully ant developers will contact you to get your testcase.

I can't attach the testcase, since its compressed size (1.4M) exceeds the
bugzilla limit for uploads. Does anyone have a server where I can upload and
link it?

I've run into the same problem with the bzip2 task. The src file was originally
837MB, but through repeatedly splitting the file I could create a 22MB test file
which when bzipped with the ant task creates a corrupt bz2 file (verified with
bzip2 -t). I'll attach this file as a testcase. If I cut the file to 21MB, ant
creates a working bz2 file.

I could reproduce this error on both Windows XP and Linux, so I changed the OS
field to "All".

The error happens with both Java 1.5.0_10 and Java 1.6.0. I also tested the
following ant versions:

Corrupted bz2 file:
Apache Ant version 1.7.1alpha compiled on April 25 2007 (nightly build)
Apache Ant version 1.7.0 compiled on December 13 2006

Working:
Apache Ant version 1.6.5 compiled on June 2 2005

I have not been able to reproduce this.
I have tested with the Knoppix.iso file as
an example of a large (~700M) file:


  
   
 
   

The resultant tar bz2 file seems ok,
tar xjf works on it and the cmp program
reports no difference:

~/learning/a/big> ls
big.iso  big.iso.save  build.xml  iso.tar.bz2
~/learning/a/big> tar tjf iso.tar.bz2
big.iso
~/learning/a/big> mkdir z
~/learning/a/big> cd z
~/learning/a/big/z> tar xjf ../iso.tar.bz2
~/learning/a/big/z> cmp big.iso ../big.iso
~/learning/a/big/z>
