Subject [jira] [Comment Edited] (COMPRESS-194) Unable to create a TAR file that contains an entry which is >8 GB in size.

Stefan,

I tried to setBigNumberMode to tarOutputStream.BIGNUMBER_STAR [ =1 ]. 
However, i found that tarring completes without any exceptions, and shows the tar archive
size as 9GB(which is my input of 9GB content file).
But ,when i tried to unzip using winrar( windows ), I was unsuccessful in opening this tar.
Got the error dialog "The archive is corrupt” 
When I tried to open the tar thru windows right click menu , I found my content file size
is 0 bytes. I have taken care to close all streams . 
I have attached my code snippet with this thread. 

Could you kindly look at my below code snippet and suggest what might be the rootcause for
this. 

Regards,
Jes

> The common-compress-1.4.1 api says it supports unlimited file sizes for tar and untar
operations. [http://ant.apache.org/antlibs/compress/]
> Only Untar operations on a file > 8GB is fixed,
> But creating a tar on a file >8GB is not working.
> When I try to do  " tarOutputStream.putArchiveEntry(archiveEntry); " 
> i get the below exception. 
> java.lang.RuntimeException: entry size '9633985364' is too big ( > 8589934591 )
