I have reverted the bzip2 output stream code, and the example
files that were provided now work. Thanks a lot for providing
the example files - they were extremely useful.

Tested with ant 1.6.5.
ant 1.6.5 works with this build file - so this is a regression.
comment #2 also says this.

Looking at the SVN repository the main change that
I can see is: revison 278185
http://svn.apache.org/viewvc?view=rev&revision=276208

which was applied as a result of:
http://issues.apache.org/bugzilla/show_bug.cgi?id=24798

this was done to make bzip2 faster and use less memory - however
on some edge cases it does seem to generate corrupt files.
I would suggest rolling back the changes.

Thanks for the test build file and data.
I can confirm that I see the same error.

Created an attachment (id=20086)
 --> (http://issues.apache.org/bugzilla/attachment.cgi?id=20086&action=view)
Testcase with datafile for which the bzip2 task creates a corrupted bz2 file

I have managed to reduce the size of my testcase to 10MB uncompressed (should
have done that earlier). Note that if I only take the last 9MB of the testcase
file, the created bzip2 file is correct.

The attached archive contains a testcase data file for which the ant bzip2 task
creates a corrupted bz2 archive and an ant buildfile which demonstrates the
behavior. The buildfile creates the bz2 archive and then executes the
command-line bzip2 -tv, which shows the error.

I tried at first to set up a script which creates files with random data of
increasing length to generate a smaller testcase, but the script ran very slow
(mainly because of /dev/random taking long to generate random data). I am also
not sure how the bzip2 algorithm behaves on pseudorandom data and if the error
will be triggered at all.

I think that to create a testcase, knowledge of the algorithms used is needed to
generate testcases for the boundary conditions; in other words you already need
to have a good idea what the error might be to write a testcase for it (and I
have no understanding of how bzip2 works).

My file was an oracle dump file.
