The zip generated by the link http://server/job/myJob/lastSuccessfulBuild/artifact/*zip*/archive.zip generates a zip file in which everything seems ok, but when you try to unzip the content with 7z for instance, it fails (compression method not supported).
I can't see anything in the logs.
BTW, the size of the file in the archive are set to 0. Could be a side effect in 7z.
It works fine with 1.531.
And finally, there was a modification of something about the compression in 1.532 related to issue
