This seems to be a very "free" interpretation of the specification to me. According to my understanding, the valid sizes of 8, 16, 24 or 28 as described in the Wikipedia article are a direct consequence of the specification which only allows for a fixed set of entries in the ZIP64 Extra Field. Already the zero-length case is questionable because a ZIP64 Extra Field should only be created if required, however we have to handle it here for backward compatibility reasons. ------------- PR Comment: https://git.openjdk.org/jdk/pull/15273#issuecomment-1679363319
