I unpacked both jar files with winrar and noticed some differences in size for a few files. One of those files is cocoon.roles for example.
I suggest you take the same approach and find out by using some compare tool to find the exact differences.
I am trying to recreate a custom built Cocoon 2.1.9 jar used by DSpace. The custom jar has a different size and checksum from the ‘official’ cocoon-2.0.9.jar, and I don't believe that there were and changes to the source code. It was likely built with certain blocks included/excluded.
Is it possible to somehow determine which blocks were included/excluded at build time by looking at an existing jar file?
