Stefan Bodewig commented on COMPRESS-16:
----------------------------------------
Two things to note:
Ant doesn't use commons-compress and I wouldn't expect it to do so, I've opened
a separate issue over there
https://issues.apache.org/bugzilla/show_bug.cgi?id=47153
javatar supports the GNU way of dealing with large files, but I wouldn't be
surprised if other tar variants did it in a different way, so it may be a good
idea to make handling of large files configurable just like the handling of
long file names is. That way if we add POSIX tar support later, we can plug in
a different strategy.

> Key: COMPRESS-16
> URL: https://issues.apache.org/jira/browse/COMPRESS-16
> Project: Commons Compress
> Issue Type: Bug
> Environment: I am using win xp sp3, but this should be platform
> independent.
> Reporter: Sam Smith
> Fix For: 1.1

> I made a TAR file which contains a file entry where the file is 10 GB in size.
> When I attempt to extract the file using TarInputStream, it fails with the
> following stack trace:
> java.io.IOException: unexpected EOF with 24064 bytes unread
> at
> org.apache.commons.compress.archivers.tar.TarInputStream.read(TarInputStream.java:348)
> at
> org.apache.commons.compress.archivers.tar.TarInputStream.copyEntryContents(TarInputStream.java:388)
> So, TarInputStream does not seem to support large (> 8 GB?) files.
> Here is something else to note: I created that TAR file using TarOutputStream
> , which did not complain when asked to write a 10 GB file into the TAR file,
> so I assume that TarOutputStream has no file size limits? That, or does it
> silently create corrupted TAR files (which would be the worst situation of
> all...)?
