Creating TAR archive of an 8 GB file causes IOException
-------------------------------------------------------
Key: SANDBOX-170
URL: http://issues.apache.org/jira/browse/SANDBOX-170
Project: Commons Sandbox
Issue Type: Bug
Components: Compress
Affects Versions: Nightly Builds
Environment: Win xp pro sp2; JDK 1.5.0_07
Reporter: Sam Smith
Yesterday I reported a bug with extraction of TAR archives:
https://issues.apache.org/jira/browse/SANDBOX-168
Today I found that when I tried to creat a TAR archive of a file that is
exactly 8 GB, that is,
(8L * 1024L * 1024L * 1024L) - 1
that it failed with the following strange error:
Exception in thread "main" java.io.IOException: request to write '32768' bytes
exceeds size in header of '-1' bytes
at
org.apache.commons.compress.archivers.tar.TarOutputStream.write(TarOutputStream.java:341)

bb.io.TarUtil$Test.test_archive_extract_fileLengthLimit(TarUtil.java:610)
at bb.io.TarUtil$Test.main(TarUtil.java:542)
The code that I used to try and create the TAR archive was the same described
in that previous bug report, so I will not repeat it here.
I was doing this in an attempt to discern if the org.apache.commons.compress
TAR code has any file size limits, since classic TAR is limited to 8 BG files
but org.apache.commons.compress supports GNU TAR long path names, so maybe it
has no file size limits either. (There appears to be no documentation about
this in the TAR code.)
What is strange is that the code first DID apparently succeed in TARing a 10 GB
file, albeit, when I tried to see if a third party piece of software (7-zip)
would extract it, that program objected saying that it did not support the TAR
format type encpuntered in the file.
Since I need to use a file size limit that is consistent with other programs, I
then tried to TAR a file of exactly 8 GB in size. This is when I encountered
the above error.
