When you use jar to compress a file voer 2GB in size, it reports the input file size incorrectly, and this the compression ration incorrectly.
# jar -cvMf base_10g.cpio.jar base_10g.cpio
adding: base_10g.cpio(in = -919863296) (out= 880247831)(deflated 195%)
#
In this case, the input file was 3.1 GB.
The output file seems to be correct.
