Q: Well, you say the two jar files are of different sizes, but you only told us the size of one of them.
A: The bad jar is 12,939 bytes. The good jar is 13,091 bytes. I create the good jar by manually updating its MANIFEST.MF file with this command:
jar uvfm my.jar META-INF/MANIFEST.MF
This command does not change the contents of the MANIFEST.MF file. All the diff tools so far show the contents and size of the MANIFEST.MF file to be the same (albeit with different timestamps). Why does this command change the size of the jar then?
Q:You also compared the file listing and you say the only difference was the timestamp on one of the elements. You’re saying that otherwise the jar files were identical?
A: I used your suggested commands and posted the results to show that the only difference was the timestamp. I also ran pkgdiff on the jars and it reported their contents were unchanged from one jar to the other.
In reviewing your suggestions I see that I ommitted the “-c” in the diff command. Here is the full output:
diff -c bad.lst good.lst
*** bad.lst 2015-06-19 08:13:45.000000000 -0500
--- good.lst 2015-06-19 08:13:37.000000000 -0500
