Yesterday I reported a bug with extraction of TAR archives:
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
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.
