> Description:
> 
>     Ant tar task with bzip2 compression option or ant bzip2 task generates
>     corrupted output for filesize of roughly 170+MB (before compression).
> 
>     This problem occurs with ant version 1.7 installed in 12/06.
>     Tested on linux with both jdk 1.5 and jdk 1.6
> 
> Work around: replace <tar compress=bzip2..> or <bzip2 ..>
>          with 2 steps: <tar ..> and <exec ...bzip2>
> 
> For example,
> 
>  Replace this:
>     <bzip2 src="${out.file}.dmp.tar"
>         destfile="${out.file}.dmp.tar.bz2">
>       <tarfileset dir="${dumps.dir}">
>         <include name="${dist.schema}.dmp"/>
>       </tarfileset>
>     </bzip2>
>  Or this:
>     <tar destfile="${out.file}.dmp.tar"
>         compression="bzip2">
>       <tarfileset dir="${dumps.dir}">
>         <include name="${dist.schema}.dmp"/>
>       </tarfileset>
>     </tar>

>       <tarfileset dir="${dumps.dir}">

>       </tarfileset>
>     </tar>

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.
