    Subject: [PATCH] Recognize JAR files as ZIP archives
    Similar to 7881ed2 that solved Ticket 4180.
    Not all JARs are reported the same by `file` utility:
    $ curl -sO https://repo.maven.apache.org/maven2/org/apache/ant/ant/1.10.9/ant-1.10.9.jar
    $ curl -sO https://repo.maven.apache.org/maven2/org/apache/maven/enforcer/enforcer-api/1.0/enforcer-api-1.0.jar
    $ file -z ant-1.10.9.jar enforcer-api-1.0.jar
    ant-1.10.9.jar:       ERROR:[gzip: Stdin has more than one entry--rest ignored] (Java archive data (JAR))
    enforcer-api-1.0.jar: ERROR:[gzip: Stdin has more than one entry--rest ignored] (Zip archive data, at least v1.0 to extract)
    $ file --version
    magic file from /etc/magic:/usr/share/misc/magic
    Above makes some JARs to be mc-viewable (reported as Zip archive),
    and some not (reported as Java archive data).
    This change allows the jar(zip) rule to work again.
