I don't think the fault lies in cp, but in your file ownerships.  cp
- --preserve only preserves Unix file permissions, not the Windows read-only
flag; I think the reason the Windows read-only flag is being set or
cleared is based on the underlying behavior of cygwin itself based on
whether your user has permission to write the file.

You probably want to run `mkgroup -l -d > /etc/group' to clean up this
listing.  Also, attaching the output of `cygcheck -svr' would be helpful.
 But notice that when you created source2.jar using Windows, it was
created with a different file owner, and that mapped to different POSIX
permissions.  Also, source.jar has permissions -r-xr-xr-x+; that trailing
+ means that there are ACLs associated with the file, so look at the
output of getfacl to see what further restrictions there are on copying
that file.  I'm not sure whether POSIX allows cp --preserve=all to
preserve ACLs.
